No Rhythm Deviation

The heart usually beats at rest 50 to 100 times per minute (equal to a R-R interval of 600-1200m seconds). The heart rate may increase to 200 beats per minute (R-R interval 300msec) during exercise.

Slow heart rate (bradycardia) is typically less than 50 beats per minute min; (R-R interval > 1200msec). Bradycardia should be noted but normally does not require medical attention unless other symptoms are observed.

Even if the Coala did not detect abnormalities, you should always consult with a caregiver if you experience symptoms of chest pain.
