Very often with someone requiring CPR has an abnormal heart rate and/or rhythm. Here is some information regarding abnormal heart rates and rhythms that you might be interested in or even hear someone discussing as you take your CPR certification for healthcare providers in Nashville.

Abnormal heart rates or rhythms are also known as arrhythmias or an abnormal heartbeat that is more or less than the normal range of 60-100 beats per minute. This is quite a symptom that can be seen on certain conditions and illnesses. This is also a threat to the body’s systems since an abnormal heart rhythm leads to inconsistency and abnormalities of the electrolyte levels, as well as the body’s oxygenation. A very low heart rate can also lead to respiratory depression which eventually results to death which should be prevented and managed.

  • Bradycardia

This is the medical term for an abnormally slow heart rate which is generally considered as the resting heart rate with a rate of fewer than 60 beats per minute. It becomes symptomatic to the patient when the heart rate falls below 50 beats per minute which is dangerous since this may lead to cardiac arrest.

In the management of bradycardia the priority with a patient who has bradycardia is direct treatment. If symptoms such as chest pain, difficulty breathing and hypotension occur, treat the patient immediately. A 0.5 atropine bolus may be administered and given every 3 to 5 minutes to a maximum of 3mg. But well conditioned athletes have resting heart rates in 50 to 40 beats per minute which will not need treatment, it is best to determine and distinguish first.

  • Narrow complex tachycardia

A narrow type of complex tachycardia has a narrow QRS complex even if tried on any type of lead. The first goal in this is to determine whether the rhythm is regular of irregular. Vagal maneuvers can be performed and it is successful in about 20% of cases. But vagal maneuvers are contraindicated if the patient has severe coronary artery disease, has a recent heart attack or a reduction in the blood volume. A vasalva maneuver (the patient bears down as if defecating, forcibly exhales while keeping the mouth closed) is also helpful and it has fewer complications compared with other methods.

  • Regular wide complex tachycardia

This type of arrhythmia is the most common. The filling time of the ventricles is short in this condition which results to the immediate fall of the cardiac output. The patients are usually unstable with this type of arrhythmia. Adenosine may be administered to treat a regular wide complex tachycardia.

  • Irregular wide complex tachycardia

Polymorphic ventricular fibrillation, aberrantly conducted atrial fibrillation and pre excited atrial fibrillation are the most common types of irregular wide complex tachycardias. Polymorphic ventricular fibrillation originates from multiple locations of the heart, a characteristic which distinguishes this type with the others. This type of ventricular fibrillation rapidly progresses into cardiac standstill so it is best to provide immediate interventions with this type of VF.


Typically these advanced rhythms are only taught in higher classes such as ACLS. However, you might have to CPR when someone is in one of these rhythms. It’s just good that you have heard of them.
