Ablation Part II

There are a many types of ablations available to patients with abnormal heart rhythms. Atrial fibrillation ablation Pulmonary vein isolation – Most atrial fibrillation (AFib) signals originate in the pulmonary veins.  Ablations are performed to create many lesions (scars) to form a circular scar around the four pulmonary veins during this procedure.  The scar thereby blocks any impulses firing from within the pulmonary veins [...]

Cardioversion Part II

Cardioversion Part II of II   Electrical cardioversion–Known as “direct-current” or DC cardioversion, a perfectly timed, synchronized electrical shock is delivered through the chest wall to the heart through paddles or special electrodes that are applied to the skin of the chest and back.   The procedure disrupts the abnormal electrical circuits in the heart; [...]

Cardioversion Part I

Cardioversion Part I of II   Cardioversion is a quick, corrective, procedure where an electrical shock is applied to the heart to convert an abnormal heart rhythm into normal sinus rhythm.   Elective or “non-emergency” cardioversions are mostly performed to treat atrial flutter (AFL) or atrial fibrillation (A Fib), non-life threatening abnormal rhythms that originate in the top portion [...]

Treatment for Arrhythmias Part II of II

Devices for Heart Failure – A cardiac resynchronization therapy (CRT) device is a special pacemaker for patients with heart failure.   The implanted device paces the left and right ventricles together.   This helps to resynchronize muscle contractions and improve the efficiency of a weakened heart. Cardioversion – Cardioversion is when an electrical shock is given to the heart to convert an abnormal rhythm back to [...]

Treatment for Arrhythmias Part I of II

Treatment for Arrhythmias To select the best treatment plan it is important to know the underlying cause of the heart rhythm disorder.   In general, it is best to treat with the least invasive option that effectively controls the heart rhythm disorder.  There are several options for treatment.   Listed below are treatment options from the least [...]

Bradycardia Part II of II

First-degree heart block:  The electrical impulses slow down as they pass through the conduction system, but the signals all eventually and successfully reach the ventricles.   First-degree heart block infrequently causes problems or symptoms.  Trained athletes may have first-degree heart block.   Some medications are known to cause this condition and treatment is generally not needed.   Second-degree heart block (Type [...]

Bradycardia Part I of II

A slow heartbeat (heart rate) is called bradycardia and is an arrhythmia, or a heart rhythm disorder.   A normal heart beats about 100,000 times per day, at a usual rate between 60 to 100 times per minute.   Changes in heart rate caused by diet, activity, age and medications are common and normal.   What [...]

Skipped Heart Beats

Skipped Beats and Extra Heart Beats It is interesting that both extra heart beats/palpitations and skipped beats are typically due to the same cause: the regular heart rhythm is interrupted by a premature or early beat.   When the premature beat arises in the atria (upper heart chambers), it is called a premature atrial contraction (PAC). [...]

Fainting Part II of II

Signs of Cardiovascular Syncope Cardiovascular syncope usually occurs suddenly.   There might not be any warning signs that person is about to faint.  Some individuals may feel the following:   Pressure, tightness, chest discomfort, and/or pain Heart palpitations (feels like a fluttering, racing, or pounding sensation in your heart) Shortness of breath   Long QT Syndrome and Cardiovascular Syncope Fainting is [...]

Fainting Part I of II

Fainting Fainting (syncope), a sudden loss of consciousness, most often occurs when blood pressure is too low (hypotension) so the heart doesn’t pump enough oxygen to the brain.   Typically, a fainting spell will last only a few seconds or minutes, before the individual regains consciousness.   Fainting is quite common and usually a single spell isn’t serious.  It [...]
