WebMar 16, 2024 · This is an ECG pattern of Ventricular Aneurysm – residual ST elevation and deep Q waves seen in patients with previous myocardial infarction. It is associated with extensive myocardial damage and paradoxical movement of the left ventricular wall during systole. There is ST elevation with deep Q waves and inverted T waves in V1-3. WebWhat does an enlarged P wave mean? If the p-wave is enlarged, the atria are enlarged. If the P wave is inverted, it is most likely an ectopic atrial rhythm not originating from the sinus node. Altered P wave morphology is seen in left or right atrial enlargement. The PTa segment can be used to diagnose pericarditis or atrial infarction.
WebThe P wave is a small deflection wave that represents atrial depolarization. PR interval The PR interval is the time between the first deflection of the P wave and the first deflection of the QRS complex. QRS wave complex The three waves of the QRS complex represent ventricular depolarization. WebP waves indicate the result of atrial activation and may be broadly classified as concentric or eccentric. A P wave morphology identical to a sinus P wave suggests sinus tachycardia, inappropriate sinus tachycardia, sinoatrial nodal reentrant tachycardia, or AT arising close to the region of the sinus node. What is normal P value in ECG?

WebFeb 24, 2024 · Schrödinger wrote: "in a Geiger counter there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges." The Geiger counter patiently watches (observes) the radioactive substance.
