ECG criteria for sinus tachycardia. Regular rhythm with ventricular rate >100 beats per minute. P-wave with constant morphology preceding every QRS complex. The P-wave is positive in lead II. Figure 1. ECG showing sinus tachycardia. Paper speed 25 mm/s. Calculate the heart rate by dividing 300 by the number of large boxes between R-waves.

This article is a guide for interpreting abnormal Sinus Tachycardia EKGs, including qualifying criteria and a sample EKG rhythnm strip. Sinus tachycardia is a fast rhythm with sinoatrial node impulses greater than 100 beats per minute.
Definition. Sinus rhythm with resting heart rate (HR) > 100 bpm in adults, or above the normal range for age in children. Normal heart rates in children. Newborn: 110 – 150 bpm. 2 years: 85 – 125 bpm. 4 years: 75 – 115 bpm. 6 years+: 60 – 100 bpm. Causes. Sinus tachycardia is usually a secondary condition.
Get the inside beat on sinus rhythm strips! This page offers an introduction to this ECG pattern, as well as providing lessons and drills for further exploration. What is a normal sinus rhythm in ECG? A normal sinus rhythm, seen on an electrocardiogram (ECG) tracing, has a regular heart rate and shape.
An EKG strip with sinus tachycardia will show a regular heart rhythm with consistent distances between R waves and P waves. P waves will be upright, the PR interval will be normal and the QRS complex will be narrow.
Sinus tachycardia is a rhythm in which the rate of impulses arising from the sinoatrial (SA) node is elevated. Sinus tachycardia is most often a normal and physiologic response, for example during exercise. However, sinus tachycardia can in some instances be inappropriate or pathologic.

At the BASIC level, we see a strip that clearly meets all the criteria for sinus tachycardia: a regular rhythm over 100/min. with P waves that look normal and all look alike. The rate is 110 per minute. The PR interval is just at the upper limits of normal at .20 second, or 200 ms.
