I am a 28 year old female who exercises and is a healthy weight. I have had problems with shortness of breath, palpitations, light-headedness, chest-pains headaches and fatigue for the past year or so. I had an EKG, wore a 24 hour mointer, and had an echocardiogram. I was told I had supraventricular tachycardia. It showed the arrythmia which from what I understand is an extra heart beat immediately after the first and edisodes of very fast pulses. My primary care physician was going to prescribe me with beta-blockers, but when I came into her office my heart rate was low at 38. She referred me to a cardiologist because she didn't want to prescribe beta blockers with such a low heart rate. Up to the time of my cardiology appointment, I periodically checked my pulse and it has been consistently low. It did not show these lows on the 24 hour moniter.
When I went to the cardiologist my heart rate was 36. After looking my tests over, he suggested I take beta-blockers. I asked about my low heart rate and he said he wasn't concerned with that. But I am concerned and confused since my primary care physician recommended against it. I am also concerned that it will make the symptoms worse since it will be slowing my heart down even more.
There are all kinds of heart medications...beta blockers, calcium channel blockers, etc. Your BEST source of cardiac treatment is a Cardiologist and if you are confused by this cardiologist's suggestion, seek a second opinion from another cardiologist. Most cardiologists are very receptive to their patients' getting a second opinion...
BEta blockers would be OK unless you develop dizziness or lightheadedness at which point they should be start. It is ok to have low heart rate as long as you aren't having any of the above symptoms from it (ie at all times since you are in that rhythm majority of the time). As far as the SVT goes, I would suggest an ablation procedure which will cure the tachycardia and obviate the need for any medications at all. A cadiac electrophysiologist is one who performs this procedure.
