Heart rate calculation: Normal range at rest is between 60-100 beats per minute (bpm). The basic way to calculate the rate is quite simple. You take the duration between two identical points of consecutive EKG waveforms such as the R-R duration. Take this duration and divide it into 60. The resulting equation would be: Rate = 60/(R-R interval) Rate control: accept atrial fibrillation and focus on symptom relief and prevention of tachycardias. Typically with beta-blockers and digoxin. Target rate is < 100 bpm. Rhythm control: trying to keep the patient in normal sinus rhythm.
