Intracardiac EP Tracings
Common Intracardiac Tracings Asked in Exams | Cardiac Electrophysiology
This video covers the most frequently tested intracardiac electrogram tracings in cardiology, cardiac electrophysiology, and EP lab–based examinations. The focus is on recognizing atrial, His bundle, and ventricular signals, understanding AH and HV intervals, and identifying common pathological patterns seen during invasive EP studies.
Topics covered include
• Components of intracardiac electrograms: A, H, V signals
• Normal atrial, His, and ventricular activation sequence
• AH interval: normal values, prolonged AH, AV nodal delay
• HV interval: normal values, prolonged HV, infranodal disease
• Differentiating AV nodal vs infranodal block on intracardiac tracings
• His bundle electrogram interpretation in AV block
• Intracardiac findings in Mobitz I and Mobitz II block
• Tracings in complete heart block
• Atrial flutter and atrial fibrillation intracardiac patterns
• Ventricular tachycardia vs supraventricular tachycardia using intracardiac signals
• Use of intracardiac tracings in EP exams and viva questions
This video is useful for cardiology residents, DM/DNB cardiology trainees, electrophysiology fellows, and anyone preparing for theory exams, practical exams, or EP lab assessments.
