Which ECG represents the condition described below: A) Sinus Bradycardia: slower than 60 bpm-very common B) Sinus Tachycardia: faster than 100 bpm-somewhat common C) 1st Degree Heart Block: AV Node delays passage of depolarization to ventricles a bit too much (PR Interval greater than 0.2 seconds) D) 2nd Degree Heart Block: Some atrial depolarizations fail to pass through the AV node (P-wave without a QRS) E) 3rd Degree Heart Block: Atrial rate different from ventricular rate (PP-Intervals different from RR Intervals) F) PVC or Preventricular Contraction: Part of ventricle becomes an ectopic foci (no preceding P-wave) and creates a depolarization with bizarre Q. R or S-waves because the depolarizations are not moving in the normal directions. PCVs often occur following hypoxia/inschemia/infarct and often leads to a fatal pattern of cardiac fibrillation. G) Ventricular Fibrillation: This irregular saw-toothed ECG pattern indicated there is no organized electrical conduction pathway in use. All parts are depolarizing in random fashion and no ventricular ejection is occurring. If this occurs, you will become unconscious in a matter of seconds (hypoxia in brain) and if the condition is not rapidly fixed, brain damage will begin in a matter of a few minutes. You have to hope the heart reverts on its own to a normal rhythm or that someone uses a “defribrillator" to return your heart of normal conduction with an electric shock. CPR is often given while you wait for a defibrillation unit to arrive! (Call 911 if this is ever observed!)
