|January 1, 1987
Summary
Coughing can trigger Mobitz type II atrioventricular block in susceptible individuals. This heart rhythm disturbance, located above the His bundle, explains cough syncope.
Area of Science:
- Cardiology
- Electrophysiology
- Neurology
Background:
- Cough syncope is a rare condition characterized by transient loss of consciousness associated with coughing.
- The underlying electrophysiological mechanisms of cough syncope are not fully understood.
- Mobitz type II atrioventricular block is a serious heart rhythm abnormality.
