I am 25 years old and have been getting dizzy spells for a month now and have checked my blood pressure frequently over the past couple weeks and it usually reads about 100/59 with my pulse being in the 50s.  Im not athletic either.  What would cause this?  Ive never had any health issues.  Im 52 and weigh 150.
Thanks for your question on Chat Doctor. I can understand your concern. You are having hypotension with bradycardia (slow heart rate). This is commonly seen with heart blocks. Your symptoms like dizziness is also seen with heart block. This is block in conduction of heart. So impulse generated in heart is not able to traverse properly and so heart pumping is poor which results in hypotension and bradycardia. If not treated promptly, this can be life-threatening. So consult cardiologist and get done 1. ECG 2. 2d echo 3. Holder monitoring (24 hours continuous recording of ECG). You will need pacemaker insertion on the basis of type and severity of heart block. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
