The P wave of an ECG indicates atrial contraction. The P wave on an ECG represents atrial contraction.

Web10 de ago. de 2024 · Normal sinus rhythm (NSR) is the rhythm that originates from the sinus node and describes the characteristic rhythm of the healthy human heart. The rate … WebThe key to interpreting this rhythm lies with beat 4, which clearly occurs earlier than expected, and which is preceded by a seemingly normal PR interval. This strongly suggests beat 4 is sinus-conducted. Note the appearance of beat 4 in simultaneously recorded leads V1, V2, and V3.

Web22 de nov. de 2024 · Normal PR Interval: The normal PR measure is greater than 0.12 s and less than 0.20 s (120 to 200 ms). Short PR interval: If the PR is less than 0.12 s indicates accelerated atrioventricular conduction. The most obvious example is the Wolff–Parkinson–White syndrome.
WebCommon findings Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant. graphic tee sayingsWebThe normal PR interval (measured from the beginning of the P wave to the beginning of the QRS complex) is 0.12 to 0.2 sec.
