Final answer:
To estimate the heart rate with the 6-second method, you would count the QRS complexes on a 6-second ECG strip and then multiply by 10. Potential estimated heart rates are 60 bpm, 70 bpm, 80 bpm, and 90 bpm.
Step-by-step explanation:
To estimate the heart rate using the 6-second method, you count the number of QRS complexes on an ECG strip that represents exactly six seconds. Each QRS complex represents one heartbeat. You then multiply the number of heartbeats by 10 to estimate the number of beats per minute (bpm). Since heart rates are typically rounded to the nearest whole number, the possible answers would be 60 bpm, 70 bpm, 80 bpm, or 90 bpm.
Without the actual data from the ECG strip, we cannot determine the exact heart rate; the formula is simply the number of beats in 6 seconds multiplied by 10. For example, if you counted 7 beats in 6 seconds, the estimated heart rate would be 70 bpm (7 beats x 10).
