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.

http://www.columbia.edu/~ss45/EKG-2.PDF WebThe point where the wave returns to the baseline marks the end of the P Wave. A QRS complex normally follows each P Wave. A normal sinus P Wave indicates that the electrical impulse responsible for the P Wave originated in the SA node and that normal depolarization of the right and left atria has occurred. SA node is the pacemaker site.

WebJul 25, 2024 · The P wave and PR segment is an integral part of an electrocardiogram (ECG). It represents the electrical depolarization of the atria of the heart. It is typically a small positive deflection from the … WebThe P-wave will display higher amplitude in lead II and lead V1. Such a P-wave is called P pulmonale because pulmonary diseases are the most common causes (Figure 3, P-pulmonale). If the left atrium encounters increased resistance (e.g due to mitral valve stenosis) it becomes enlarged (hypertrophy) which amplifies its contribution to the P-wave.

WebFeb 15, 2024 · The P wave on an ECG trace is indicative of atrial depolarisation, which may be initiated by the sinoatrial node or by an ectopic atrial focus. Normal P Wave Size Duration <120ms (3mm) Amplitude <2.5mm The P wave is directed inferiorly and therefore should …

WebP waves are the key to determining whether a patient is in sinus rhythm or not. If P waves are not clearly visible in the chest leads, look for them in the other leads.
