WebSinoatrial arrest occurs when the sinoatrial node does not discharge an impulse for ≥2 seconds. Failure to discharge an impulse within <2 seconds is defined as sinoatrial pause. Refer to Figure 1. Figure 1. Sinoatrial arrest. Also note the ST-segment elevations (which in this case has no relation to the sinoatrial arrest).

Supraventricular Tachycardia (SVT) • LITFL • ECG Library Diagnosis

WebIn sinus rhythm the P wave is a low energy impulse that moves towards the lead, making it a short bump that goes above the isoelectric line. It's followed by the QRS which shoots down the septum, directly towards lead II making a BIG spike and then wraps back up the ventricles, sometimes leaving a little dip below the isoelectric line before the impulse ends. WebA rhythm is defined as three consecutive beats with identical waveforms on the ECG. The similarity of the waveforms indicates that the origin of the impulse is the same. The sinoatrial (SA) node is the heart’s pacemaker under normal circumstances and the rhythm is referred to as sinus rhythm. Hence, sinus rhythm is the normal rhythm of the heart. tatuaggi urbex

WebCardiology. Left anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, [1] [2] related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the left anterior fascicle – one half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation.
