Note: A first-degree AV block is also part of a trifascicular block, as the AV node is sometimes considered the third fascicle. ECG Examples: First-Degree Atrioventricular (AV) Block ECG (Example 1) ...

Healthcare professionals may also call this condition first-degree atrioventricular (AV) block. It is a type of arrhythmia, or abnormal heartbeat. There are three degrees of heart block — first ...

When 2:1 AV block is present, the rhythm may be second-degree type I or second-degree type II AV block. Exercising the patient will increase AV nodal conduction and help distinguish these two.

The diagnosis is NSR, first-degree AV block, 3:1 AV block, Mobitz type II, and high-degree AV block. The rhythm is regular with a rate of 30 beats/min. The QRS complex duration is normal (0.08 sec ...

The diagnosis is normal sinus rhythm, first-degree AV block (prolonged AV conduction), premature ventricular complexes, escape junctional complex, left ventricular hypertrophy with associated ST-T ...

A first degree AV block is when the electrical signal is simply slowed a bit more than usual but not to the point that you end up skipping any heart beats.

Dear Dr. Donohue: My EKG showed "sinus rhythm with poor R wave progression. Borderline first degree AV block. Consider anteroseptal infarct." I was then given a radioactive stress test, preceded ...

Nearly 90% had atrial fibrillation at baseline, 5% had first-degree AV block, 33% had right bundle branch block (RBBB), and 7% had LBBB, left anterior fascicular block (LAFB), or left posterior ...
