Key result
Antiarrhythmic drugs are linked to arrhythmia aggravation in ~32% of patients.
Why the study?
The usefulness of antiarrhythmic drugs is limited by frequent side effects including aggravation of the arrhythmia being treated, which is a serious complication.
Do antiarrhythmic drugs cause aggravation of arrhythmia in patients undergoing noninvasive drug testing?
Observational (n=245)
Do antiarrhythmic drugs cause aggravation of arrhythmia in patients undergoing noninvasive drug testing?
Antiarrhythmic drugs can paradoxically aggravate arrhythmias, a potentially serious complication observed in nearly a third of tested patients.
No takes yet. Share an insight, caveat, or question.
Proarrhythmic aggravation during noninvasive testing warrants vigilant monitoring; leaves open whether findings alter drug selection or long-term outcomes.
Philip J. Podrid (1984) conducted an observational in Arrhythmia (n=245). Antiarrhythmic drugs was evaluated on Aggravation of the arrhythmia being treated. Antiarrhythmic drugs aggravated the treated arrhythmia in 11% of 1024 single drug tests, with at least one drug being proarrhythmic in 32% of the 245 patients.
