Final answer:
To determine the ventricular rate using the memory method, count the number of R waves in a six-second time period and multiply it by 10 to get the rate in beats per minute.
Step-by-step explanation:
To determine the ventricular rate using the memory method, we count the number of R waves in a six-second time period and multiply it by 10 to get the rate in beats per minute.
For example, if there are 8 R waves in the six-second ECG strip, the ventricular rate would be 8 * 10 = 80 beats per minute.
