wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction.
BASIC ECG INTERPRETATION – RST WORKSHEET #5 Instructions: Calculate the Atrial Rate*, Ventricular Rate*, PR interval, QRS width, and Interpretation for each strip. *Calculate the Atrial and Ventricular Rate using either the 1500 method, countdown method or 6 second method 1. Rhythm: Atrial: Ventricular:

9 Αυγ 2024 · Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart’s electrical activity as waveforms.
8 Νοε 2021 · Our EKG Interpretation Cheat Sheets provides information on reading EKG strips with over forty different abnormal EKG examples. For each arrhythmia, there are EKG strip examples and descriptive text with qualifying criteria.
The electrocardiogram (ECG) is a tool for recording and interpreting cardiac activity through repeated cardiac cycles. NSR is the default, healthy cardiac rhythm. The electrical impulse originates from the sinoatrial (SA) node and the ECG strip will demonstrate the following characteristics:
