context_page_description: Rhythm interpretation is an important part of healthcare in Emergency Medical Services. Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia. Rhythms can be evaluated by measuring a few key components of a rhythm strip, the PQRST sequence, which represents one cardiac cycle, the ventricular rate, which is the rate at which the ventricles contract, and the atrial rate, which is the rate at which the atria contract.
context_section_description: Ventricular arrhythmias are some of the most dangerous heart rhythms requiring cardiopulmonary resuscitation (CPR) and defibrillation in cases of symptomatic Ventricular tachycardia and Ventricular Fibrillation.
  There are 5 different ventricular arrhymia.
  Ventricular Tachycardia is a regular rhythm with a rate of 140-250 bpm, there are no P waves and the main feature is a wide QRS complex (0.12 and greater)
  Ventricular Fibrillation has no p waves or QRS complexes, there are only wavy irregular deflections throughout the heart rhythm, at this point the heart would have a rate of 0 and be supplying no blood through the body.
  Idioventricular rhythm this is a regular rhythm identifiable by a wide QRS complex with absent P waves, and a rate between 30-40 bpm.
  An Accelerated IVR is also a regular rhythm with a wide QRS complex and absent P waves, however the rate is between 50-100 bpm.
  The final rhythm is Ventricular Standstill this rhythm will appear as a flat line, but may have a few non conducted p waves, the heart rate of this will be 0 and be supplying no blood through the body like ventricular fibrillation.
