Ekg Heart Diagram. Chest precordial electrodes and placement v1 fourth intercostal space at the right border of the sternum v2 fourth intercostal space at the left border of the sternum v3 midway between placement of v2 and v4 v4 fifth intercostal space at the midclavicular line. Count the number of complexes on the rhythm strip each rhythm strip is typically 10 seconds long.
Read an ekg. This stimulation is also called activation or excitation. Chest precordial electrodes and placement v1 fourth intercostal space at the right border of the sternum v2 fourth intercostal space at the left border of the sternum v3 midway between placement of v2 and v4 v4 fifth intercostal space at the midclavicular line.
The right and left bottom chambers or ventricles make the next wave called a qrs complex.
Well labelled diagram of heart. The ekg produces a distinctive waveform in response to the electrical changes taking place within the heart. We see below the precordial leads in their relationship to the heart and chest anatomy. The right and left atria or upper chambers make the first wave called a p wave following a flat line when the electrical impulse goes to the bottom chambers.
