The reference line was set as the summit of QRS for the surface ECG, and electrical delay was measured in milliseconds between the reference line on the surface ECG and the onset on the bipolar intracardiac electrogram. We collected the activation potential (reflected by the activation time) point by point when pulling back the lead and determined that the purple area was the latest activated region while the white one was the earliest.

Cardiac Resynchronization Therapy-Pacemaker Implantation Guided by Three-Dimensional Electroanatomic Mapping for a Chinese Young Man with Danon Disease

Comparison of quick optimization of interventricular delay between simple methods: intracardiac electrogram and surface electrocardiogram after cardiac resynchronization therapy.

MANUAL INTRACARDIAC ELECTROGRAM METHOD IS ACCURATE ALTERNATIVE TO ECHOCARDIOGRAPHY FOR ATRIOVENTRICULAR AND INTERVENTRICULAR OPTIMIZATION IN CARDIAC RESYNCHRONIZATION THERAPY

Intracardiac electrograms revealed a repetitive, high-frequency artifact on the ventricular channel interwoven with regular atrial and ventricular sensing (Figure 1).

Electromagnetic Interference from Swimming Pool Generator Current Causing Inappropriate ICD Discharges

For each ICD-recorded episode of tachyarrhythmia, the date, time, beat-to-beat intervals, and intracardiac electrogram before, during, and after episodes were recovered from the ICD.
