40-60 BPM , Occurs in drug overdoses

Sinus arrhythmia

60-100 BPM All complexes normal

Normal Sinus rhythm

60-100 bpm , Normal Heart rate

Atrial Flutter

Atrial rate - 400 BPM Ventricular rate - 60-100 BPM

Asystole

Death No electrical activity Do not shock

Loose or Broken wires

Loose or broken lead wires

V-fib

No pulse, but has electrical activity- You can shock the patient, CPR, Medication,You can do defibrillator

Atrial Fibrillation

P waves replaced by small F waves Atrial rate- 350-600 BPM

Premature atrial Contraction

SA node fires too soon No break between heart beats

Baseline Shift

Sensors too loose or too tight, too little electrolyte, Dirty sensors

Ac interference

arc-like bands that occur when the machine is too close to an unshielded electrical device

Somatic tremor

caused by the patient tensing or contracting a muscle during test

Premature ventricular contraction

early firing off the ventricles
