Procedure 1 Correlating Points on an ECG with Electrical Events of the Heart Let's start by correlating the following points on the ECG with the electrical activity occurring in the heart Identify the electrical events taking place in cardiac cells at each of the six points int the ECG in Figure 19.8, and explain the events in the answer lines provided. Do remember though that the ECG shows only electrical events, not mechanical events. A heart can have electrical activity...

AAAAA Label P. QRS, and Twaves on the ECG strip in Figure 4.5. Figure 1.5: ECG strip. DETERMINE HEART RATE FROM AN ECG The range of normal heart rates is called normal sinus rhythm (NSR). In an average adult NSR is between 60 and 100 bpm. A heart rate below 60 bpm is called bradycardia. However, a highly acro bically conditioned persons often have a normal heart rate below 60 bpm. A heart rate above 100 bpm in an adult...

In an adult, a heart rate of 60-100 beats/min is a normal sinus rhythm (NSR). A heart rate at or above 101 beats/min is called tachycardia, but in young children, this rate would be considered normal. Heart rates belovw 60 beats/min are normal for highly conditioned individuals, but in most adults this is bradycardia I. Calculate the heart rate for the ECGx.0 Diagnosis P-R intervals: Normal P-R intervals are between 0.12 and 0.2 seconds, averaging about 0.16 seconds. P-F intervals...
