With this calculator, you will be able to acquire your patient’s heart rate from an ECG. You will only need to measure the distance between two R wave peaks – the RR interval. You can use either a ruler or a caliper and type in the result in millimeters or quantity of ECG boxes, you choose!
But remember! If RR intervals between at least two ECG complexes are different, your patient might have an arrhythmia, and our calculator may give you a false result. Don’t forget to check it!
