Supraventricular Tachycardia

Its been a tough 2011 and the start of 2012 is no good as well. But still faith and hope that all goes well as we go  through the year. My son has been diagnosed with this heart disorder that I couldn't even spill right... Supraventricular Tachycardia.

Well for those who are suffering or have someone that is enduring the same malady, here's some information that might be of help to you.

Supraventricular tachycardia (SVT) is a general term that refers to any rapid heart rhythm originating above the ventricular tissue. Supraventricular tachycardias can be contrasted to the potentially more dangerous ventricular tachycardias - rapid rhythms that originate within the ventricular tissue. Although technically an SVT can be due to any supraventricular cause, the term is often used by clinicians to refer to one specific cause of SVT, namely Paroxysmal supraventricular tachycardia (PSVT) which is due to AV nodal reentrant tachycardia.

Supraventricular Tachycardia Causes

Paroxysmal, or sporadic, supraventricular tachycardia usually occurs without other symptoms. However, it may be associated with a number of medical conditions, such as the following:

  • Hardening of the arteries (atherosclerosis) 
  • Heart failure 
  • Thyroid disease 
  • Chronic lung disease 
  • Pneumonia 
  • Pulmonary emboli, or blood clots migrating into the lung arteries from elsewhere in the body 
  • Pericarditis 
  • Certain drugs and social habits 
  • Cocaine abuse 
  • Alcohol abuse 
  • Smoking 
  • Drinking too much caffeine in coffee, tea, or soft drinks 
  • Emotional stress 

Structural abnormalities, such as Wolff Parkinson White syndrome, in which extra electrical tissue sets up abnormal electrical circuits
Supraventricular tachycardia may also be a side effect of medications such as digitalis, asthma medications, or cold remedies.
In some cases, the cause of supraventricular tachycardia is unknown.

Supraventricular Tachycardia Symptoms

Paroxysmal supraventricular tachycardia (PSVT) can cause a number of symptoms, depending on your overall health and how fast your heart is beating. People with heart damage or other coexisting medical problems experience a greater degree of discomfort and complications than those who are healthy. Some people have no symptoms at all.

Symptoms can come on suddenly and may go away by themselves. They can last a few minutes or as long as 1-2 days. The rapid beating of the heart during PSVT can make your heart a less effective pump so that your body organs do not receive enough blood to work normally. The following symptoms are typical with a rapid pulse of 140-250 beats per minute:

  • Palpitations - The sensation of your heart pounding in your chest 
  • Dizziness, or light-headedness (near-faint), or fainting 
  • Shortness of breath 
  • Anxiety 
  • Chest pain or tightness

When to Seek Medical Care

Supraventricular tachycardia is generally not life threatening unless you have other heart disorders. Call your health care provider if any of the following conditions occur:

  • The episode of rapid heartbeat or palpitations is your first, and the symptoms last longer than a few seconds to a minute or two. 
  • You have had previous episodes of supraventricular tachycardia, and the current episode does not go away with vagal maneuvers (coughing, deep breathing, or muscle tensing).
  • The following conditions warrant a visit to the nearest hospital emergency department. Do not drive yourself to the hospital. Call 911 for emergency help.
  • You have rapid heartbeat and feel dizzy or faint. 
  • You have rapid heartbeat with chest pain. 
  • You feel short of breath with rapid heartbeat.

Toshiba 40" LCD HDTV

Its been a great 2010 Christmas! Got a huge present from my in-laws!
So far so good. The sleek and slim, shinny look works well for us (hopefully my three little angels won't damage it :) Good enough for first timers on LCD HDTV...

Key Features:

    *  1080p HD resolution (1920 x 1080 pixels)
    * 60Hz screen refresh rate
    * CineSpeed LCD panel with a fast response speed necessary for cleaner high-action home theater images. A wide viewing angle ensures that you'll have the best seat in the house.
    * DynaLight Backlight Control utilizes advanced image processing to monitor the brightness of each video frame, and adjust the backlight intensity accordingly. This precision creates seamless transitions with deep blacks for increased detail and depth analysis.
    * Photo Frame capability allows this HDTV to act as both a TV and a digital photo frame. You can showcase your favorite memories as a clear, crisp slide show on the high-resolution television screen--all controlled with just the TV remote.
    * Gaming Mode takes the gaming experience to a new level by reducing game control delay, thus giving the player improved reaction time and a more realistic playing experience. This is great when used with popular gaming consoles, or with PC games using the TVs PC Input.
    * Built-in ATSC/NTSC/QAM digital tuning allows for tuning of standard cable channels as well as off-air digital broadcasts, in addition to digital "cable-in-the-clear" broadcasts.
    * Native Mode restores the size of the picture by the 3-5 percent that is generally lost during the normal over-scanning that occurs on traditional sets.
    * Cinema Mode 24 fps (3:2 Pulldown): This HDTV performs 3:2 pulldown detection and reversal, too--a handy feature for watching progressive-scan movie programs in their native 24-frame format. To adapt 24 frames-per-second movies to 30 fps video, frames in the original movie must be duplicated; 3:2 pulldown digitally corrects this duplication by removing the redundant information to display a frame-accurate picture.
    * Color Temperature Control enables you to adjust white balance to achieve the best television picture possible in any viewing environment, or simply adjust the picture to suit your personal tastes. The "Warm" setting delivers a redder image that is ideal for display in a dimly lit room, while "Medium" and "Cool" provide a progressively bluer image for the best picture as room light levels are increased.
    * Three TheaterWide modes are ideal for displaying HDTV signals as well as enhanced for widescreen television DVDs.

          o TheaterWide 1: Letterboxed image is digitally expanded 33 percent horizontally and vertically. Useful for reproducing Academy Standard (1.85:1) formatted software.
          o TheaterWide 2: Letterboxed image is expanded 33 percent horizontally and 42 percent vertically. Particularly of use when viewing narrow letterboxed images originally filmed in Panavision or CinemaScope.
          o TheaterWide 3: Letterboxed image is expanded 33 percent horizontally and 24 percent vertically. Can be utilized when displaying letterboxed images that incorporate narrow bands at the top and bottom of the picture.

    * MP3 audio and JPEG image playback via USB port on the side.
    * REGZA-LINK (HDMI-CEC) allows peripheral AV devices such as a DVD player to be controlled by the remote control.
    * InstaPort fast HDMI switching between A/V components: Typically, when you switch HDMI inputs, there can be a five or six second delay. With InstaPort, as soon as you select an HDMI source, it will connect in a fraction of the time.
    * Bottom-mounted invisible speakers integrated into stylish Horizon bezel design (20 Watts total power; 10W + 10W).
    * Channel Browser allows you to easily scan through the last 32 channels you have viewed, with screen images for the last five channels displayed, by channel, by favorites, and by input, at the touch of a button.
    * Channel Labeling allows you to put station call letters on the screen along with the station numbers, so you always know what channel you're watching
    * Input labeling enables you to name the individual inputs to denote usage, such as "DVD Player" (instead of having them display as just "HDMI 1" and "HDMI 2").
    * Removable stand for wall mounting (200mm x 200mm VESA mounting pattern)
    * Tri-lingual onscreen menu (English, French, Spanish)
    * Warranty: 1-year limited warranty on parts and labor

Ugly skin rashes!!! Pityriasis rosea..

Lately I've been having trouble with this disgusting rashes that I had on my skin. Four days of headache at first and then the spread of the awful virus! That is according to the derma where I had my skin checked, it's a viral allergy called Pityriasis Rosea. "Doc.. can you please write it down so can surf the web for it. You know for further info" although the doctor has been generous enough to share all the need-to-knows of the virus, I just feel like browsing it up :)

And here's what I found out...

Pityriasis rosea is a skin rash that often sweeps out from the middle of your body, with a shape that resembles drooping pine-tree branches. Pityriasis (pit-ih-RI-uh-sis) rosea usually begins as one large spot on your chest, abdomen or back and then spreads.

Although pityriasis rosea has a distinctive appearance once the rash spreads, in its early stages you may confuse pityriasis rosea with other skin disorders.

Pityriasis rosea can affect any age group, but commonly affects older children and young adults. It usually goes away on its own, but may last for several weeks. Before it disappears, pityriasis rosea may make you mildly uncomfortable, but there are steps you can take to relieve your discomfort.

The exact cause of pityriasis rosea is unclear, although the cause may be a viral infection, such as infection with certain strains of the human herpes virus (HHV6 or HHV7). Pityriasis rosea, however, isn't believed to be contagious. (This is a relief cause people were looking at me as if I have AIDS or something!)

Well you can read more through

I wanted to share this for those who does not have any idea of what the virus is. Personally, I regret not paying attention to it the first time. Now its all over me! Hope the prescription works! :)
