Heart Problems


Sent to Health Experts May 01, 2006 5:37 p.m.
I am 27 years old. Two years ago I experienced Cardiac Arrest due to low potassium. After my follow up visit with the Cardiologist, I was told I have SVT. I've had holter monitors that showed several runs of SVT and also 2 Atrial Runs. I've had EKG's show premature atrial contractions and an EKG from yesterday's ER visit that showed a short PR Interval.   What is the significance to these finding and what exactly do they mean.

SVT stands for supraventricular tachycardia, runs of these can be anywhere from a few beats to several minutes. These beats originate in one of the top two chambers of your heart. I am sure you kept a log while you wore the Holter monitor, yes? What did you document at the time that these beats were happening? PACs are premature atrial contractions. These atrial beats are also coming from one of the top two chambers of your heart, but they are likely single beats. Atrial runs occur when these beats do not stop after one or two. These SVTs and atrial runs are faster than your normal heart rate. Usually as fast as 120-180/minute. This can make you dizzy, lightheaded, and you could faint if it goes on for very long. People of your age (with strong heart muscle) can tolerate it better than older folks. the PR interval is the electrical activity that occurs and is seen on the EKG from the time the atria start to contract until the ventricles start to contract. When shortened it generally means that the time in this section of activity is shorter than usual, perhaps because the electical activity of the new beat begins in a focus or area that is different from the normal sinoatrial (SA) node. This is a collection of nerve fibers that fires a bit of "electricity" to start the heart at the begining of each cyle. Are you on any medicines to keep the tachys under control?
