Cardioversion is used to correct abnormal heart rhythms, also known as arrhythmias. Electrical cardioversion may be recommended for you if you have certain types of arrhythmias, such as: Atrial fibrillation (AFib): This is the most common type of arrhythmia, and it can cause symptoms like dizziness, fatigue, and difficulty breathing.
Hopefully a repeat echocardiogram will be performed outpatient. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). NOTE: Prediction of cardiac contusion "severity" on the basis of cardiac arrhythmias and ECG findings — is an imperfect science. QTc prolongation.
PEARL #1: The most commonly overlooked arrhythmia is AFlutter ( A trial F lutter ). At the time, it seemed that virtually all cardiac patients with chronic AFib or heart failure were on this medication. IV Digoxin may begin to slow the ventricular response of AFib or AFlutter sooner than many clinicians realize.
Case sent by Magnus Nossen MD, edits by Meyers A previously healthy woman in her 60s presented to an outpatient clinic for palpitations. Patient was referred to electrophysiologic testing due to suspicion of afib and WPW. During electrophysiologic testing AVRT was induced, which degenerated to afib with ortho and antidromic conduction.
If the patient does not present with syncope, then outpatient management is probably OK, with referral to cardiology. Taking a Closer LOOK : There is a fairly marked sinus arrhythmia ( RED arrows in Figure-2 ). PEARL # 1: It is common with 2nd- and 3rd-degree AV block to see a "ventriculophasic" sinus arrhythmia.
