Some Medications That Cause Syncope
Mechanism | Example |
|---|---|
Bradyarrhythmia | Beta-blockers Calcium channel blockers (not dihydropyridines) |
Tachyarrhythmia | Any medication that prolongs repolarization* (eg, some antiarrhythmics, some antipsychotics, some antidepressants, some antihistamines, some fluoroquinolones) |
Most antihypertensives (rarely beta-blockers) Antipsychotics (mainly phenothiazines) Nitrates (with or without a phosphodiesterase inhibitor for erectile dysfunction) Tricyclic antidepressants | |
