Just over a year ago, after wearing a Mobile Cardiac Arrhythmia Diagnostic System (loop monitor) for two weeks, I was diagnosed with Paroxysmal Supraventricular Tachycardia (PSVT). The doctors had been doing a bunch of different tests on my heart at the time because my heart was not beating regularly, and I had a frightening health scare several weeks prior.
This explained the sudden rapid heartbeats that were causing my unusual shortness in breath, and why my heart often jumped from 70 bpm to 230 bpm in a matter of seconds. My heart would literally shift into overdrive without warning, and I felt like I was running a marathon even at rest. (And anyone around me could physically see my heart pumping through my clothes. Scary!)
Although I remember these episodes in high school, they were never as frequent as they had become in my late thirties. I am told they only get worse with age and my lifestyle most likely did not have anything to do with it because I am a non-smoker, eat healthy, and not overweight. It is a mechanical "short circuit" problem.
But surprising to some, I was actually relieved when I found out that I had PSVT because to treat this, cardiologists are able to locate and remove this alternate pathway and prevent this bypass from occurring. I was getting more and more out of breath going up and down stairs and this was very unusual for me, as I was only 39 at the time. Needless to say, I had to get to the bottom of my condition and figure out next steps so I could feel normal again...
What I've learned:
PSVT means there is a short circuit in the heart that bypasses the desired pathway to make blood flow occur normally, which enables the heart to beat excessively fast. Since PSVT results in a significant increase in heart rate beyond what the heart is really designed to do, frequent and prolonged attacks can also cause damage to the heart muscle. In a typical heart attack, there isn't enough blood flow to the heart (supply) due to blockage of the arteries; but in the PSVT heart attack scenario, there is excess demand due to the rapid heart rate, and the body can't supply enough blood flow to meet it. Depending on the amount of damage, this could lead to poor functioning of the heart and eventually heart failure.
