What does it mean by aberrant conduction?

Aberrant conduction is defined as conduction through the atrioventricular node with delay or block, resulting in a broader QRS complex. Aberrant conduction usually manifests as left or right bundle branch block, both of which have characteristic features.

Is atrial bigeminy serious?

Atrial bigeminy, as a manifestation of PACs, is a harmless rhythm in the proper clinical context. Most people with PACs do not have organic heart disease, although PACs are more common in patients with heart disease than in those without.

What is aberrant conduction in ECG?

Aberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period. This is explained by the changes of the refractoriness in the His-Purkinje system related to changes in the RR interval.

What is atrial bigeminy?

Atrial bigeminy is a sinus rhythm that occurs when every other beat is a premature atrial contraction (PAC). Clinical Significance. Atrial bigeminy is a manifestation of PACs; therefore, in most cases it is a harmless rhythm.

What does aberrant mean in medical terms?

Aberration: (1) A deviation or irregularity. For example, a chromosome aberration is a deviation from the normal chromosome number or the normal chromosome structure. In this sense, aberration is also synonymous with deflection, departure, divergence, diversion, turning.

How do you treat atrial bigeminy?

Calcium channel blockers or anti-arrhythmic drugs such as amiodarone (Cordarone, Pacerone) or flecainide (Tambocor) are other drugs your doctor might prescribe. If your bigeminy is having a severe effect on your heart, you could need cardiac ablation.

When should I be concerned about atrial bigeminy?

Bigeminy is not usually a cause for concern. However, a person should seek prompt medical attention if any of the following symptoms accompany their palpitations: lightheadedness or dizziness. feeling faint.

Is atrial bigeminy a sinus arrhythmia?

Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat….

What is atrial fibrillation with aberrant conduction?

Aberrancy, or aberrant conduction just means that the beats do not get conducted along the traditional conduction pathway. Atrial fibrillation with a right bundle branch block or left bundle branch blocks are good examples of atrial fibrillation with aberrancy.

Does aberrant mean abnormal?

deviating from the ordinary, usual, or normal type; exceptional; abnormal. an aberrant person, thing, group, etc.
