Unexplained syncope
An_254900 posted:
Hello, I am a 21 year old female. I have been passing out randomly for about 5 years now. I go to a cardiologist regularly, and have had many tests (echos, tilt table, ekgs, holter monitor, event monitor, etc.). The only thing my cardiologist can tell me is my blood pressure and pulse rate drop dangerously low. Blood pressure as low as 60/30, and pulse as low as 30. Cardiologist put me on midodrine 5mg 3 times a day, and I've been on it for 5 weeks now. I have passed out 3 times since he put me on the medication. When I have an episode, I generally feel crappy for at least a day after. My blood pressure and pulse stay low, I feel nauseous, pale, cold, and weak. My cardiologist says it's not POTS, vasovagal syncope, and my heart itself has no abnormalities. We know that my blood pressure and pulse drop, but can't explain why. What should I do? Try more medications, push for a pacemaker to fix the problem?

Discuss all other viable treatment options with your cardiologist, and feel free to seek a second opinion/see other doctors.

Info for the masses

In general, causes of passing out/fainting/syncope include vasovagal (the most common cause), cardiac (includes specific irregular heartbeat, typically duration-dependent), circulatory, neurologic, metabolic and drug-induced. Sometimes, there is no known cause (idiopathic), no identifiable cause.

Additionally, of the different types of heart conditions, various symptoms can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic, or even be silent.

Best of luck down the road of life. Live long and prosper.

Be a questioning patient. Talk to your doctor and ask questions. Studies show that patients who ask the most questions, and are most assertive, get the best results. Be vigilant and speak up!"
