The second ECG strip below shows an ectopic atrial rhythm. Note that the P wave is down in lead II and only up (not biphasic) in lead V1. Ectopic atrial rhythms including atrial tachycardia, ...

This is a full 10-second rhythm strip, and there are nine QRS complexes total. Multiply the number of QRS complexes by six, and the exact heart rate is 54 bpm. There is one P wave for each QRS ...

In fact, in 3° AV block, the atrial rate can be slower than that of the escape rhythm if the patient has sinus node dysfunction and the sinus rate is slower than that of the escape rhythm or if ...

In addition, the V1 rhythm strip clearly shows a P wave in front of each QRS with a fixed PR interval. This tracing is from a patient who had a heart transplant; the recipient atrial cap is in ...

6 How is atrial activity related to ventricular activity? A P wave precedes each QRS complex throughout the rhythm strip. The distance between the P wave and the QRS complex is less than one large ...

Nevertheless, three in five (60.4%) said they would feel confident in ruling out atrial fibrillation on a 30-second single lead ECG rhythm strip. One in four (25.3%) GPs reported no obstacles to ...

Figure 4: Three electrocardiographic rhythm strips recorded in the same patient over a 6-hour period after initiation of an anti-arrhythmic drug to treat atrial fibrillation.

An electrocardiogram (ECG) and rhythm strip showed new atrial fibrillation with a rapid ventricular response. Treatment with metoprolol succinate and dabigatran was initiated, and during ...
