Question

Using the sequence method, select an R wave that falls on a dark vertical line. Number the next 6 consecutive dark vertical lines as follows: 300, 150, 100, 75, 60, and 50. Note where the next R wave falls in relation to the 6 dark vertical lines already marked"this is the heart rate. What is the heart rate?

Answer 1

To determine the heart rate from an ECG using the sequence method, an R wave is selected on a dark line, and consecutive dark lines are marked with numbers representing the heart rate in bpm, with the next R wave indicating the actual rate.

Step-by-step explanation:

The question pertains to determining the heart rate using an electrocardiogram (ECG) by employing the sequence method. To calculate the heart rate, one should select an R wave that aligns with a dark vertical line on the ECG. Subsequently, consecutive dark vertical lines should be numbered as 300, 150, 100, 75, 60, and 50. These numbers represent the heart rate in beats per minute (bpm) if the next R wave falls on that line. For instance, if the following R wave aligns with the second dark line after the reference R wave, the heart rate would be 150 bpm.
