Pseudo-retrograde conduction in complete A-V heart block due to ectopic His bundle activity
Acta Cardiologica
|January 1, 1976
Summary
This study reports a rare case of complete atrioventricular heart block with parasystolic junctional activity causing retrograde P-waves. Atropine administration helped to differentiate the ectopic beats from the underlying heart block.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Arrhythmias
Background:
- Complete atrioventricular (A-V) heart block is a serious condition affecting cardiac conduction.
- Retrograde P-waves can indicate junctional or ventricular activity influencing atrial activation.
- Parasystole is a rare arrhythmia characterized by the independent discharge of an ectopic pacemaker.
