Notice that there are several deflections from the isoelectric point that occur during the cycle. ... all are generated during ventricular depolarization we typically refer to these three waves collectively as the QRS complex. The Q wave is the first downward deflection and then back to isoelectric, the R is ... WebThe hallmark of atrial fibrillation is absence of P-waves and an irregularly irregular (i.e totally irregular) ventricular rate. The baseline (isoelectric line between QRS complexes) is characterized by either fibrillatory waves (f …
WebThe term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular atrial, and regular atrioventricular tachycardias. It is often used synonymously with AV nodal re-entry tachycardia (AVNRT), a form of SVT. In the absence of aberrant conduction ... WebThe term asystole simply refers to an absence of ventricular activity, which means the patient will exhibit no discernible electrical activity on an ECG readout. In most cases, asystole is a lethal arrhythmia and survival is …
WebJan 20, 2024 · An electrocardiogram is a test performed by placing electrodes on the chest, arms, and legs to record the activity of the heart. This test is used to detect an irregular heartbeat and damage to the heart muscle or tissue. An echocardiogram uses high-frequency sound waves to take a picture of the heart. WebPremature ventricular complexes discharged by the same ectopic focus will typically have similar morphology (appearance) and constant timing. Such premature ventricular complexes are referred to as monomorphic (or …
