In certain circumstances, the heart rhythm might be evaluated by electrophysiological studies, where the electrical system of the heart is mapped out. The process is similar to a heart catheterization, but the catheter enters a vein instead of an artery. The long catheter and electrode is guided into the heart and used to evaluate the electrical pathways inside the heart muscle. In addition to being diagnostic, sometimes short circuits may be found and treated by ablation or destroying the abnormal circuit. Wolff-Parkinson-White syndrome is often treated in this way.
You may feel palpitations in your chest, throat, or neck during activity or when you are sitting still or lying down. Strong emotions, physical activity, some medicines, caffeine, alcohol, nicotine, or illegal drugs may cause palpitations. Medical conditions such as thyroid disease, low blood sugar, anemia, and low blood pressure also may cause palpitations. Heart palpitations may be a sign or symptom of arrhythmia, an irregular heartbeat, or other heart conditions such as heart attack, heart failure, heart valve disease, or cardiomyopathy.
However, just recently, the past few months they have been occurring more frequently and are longer in duration. One episode lasted 35 minutes in the middle of the night. That caused me a lot of anxiety. I was concerned because my Dad had A-fib and his symptoms were almost exactly like what I was experiencing. So, I went to my Dad’s cardiologist. He also did a stress echo, resting echo, EKG, etc. Nothing showed on the tests, so he had me wear a monitor for a week. Luckily, I had an episode while wearing the monitor. The monitor showed that my palpitations (supraventricular tachycardia) were caused by an electrical short circuit in my heart. It is not serious, just disturbing to experience, as you all know. The doctor could see the general where the problem occurred. Medication really doesn’t help. So, I could either live with this issue or have a cardiac ablation done.
