61 Possible Causes for Irregular Heart Rhythm, Short PR Interval

  • Myocardial Infarction

    The test shows how fast the heart is beating and its rhythm (steady or irregular).[] The heart muscle which is injured in this way can cause irregular rhythms which can be fatal, even when there is enough muscle left to pump plenty of blood.[] Overview An EKG can show how fast your heart is beating, whether the rhythm of your heartbeats is steady or irregular, and the strength and timing of the electrical impulses[]

  • Chronic Obstructive Pulmonary Disease

    Rhythm Center who diagnose heart rhythm irregularities, and experts in the insertion and management of devices that correct heart rhythm.[] Giddiness or near fainting episodes may be seen sometimes and fast irregular heart rhythm usually occurs in older patients.[] If you have an irregular heart rhythm, your doctor might prescribe antiarrhythmic medications, such as amiodarone.[]

  • Atrioventricular Junctional Rhythm

    Racial disparities seen in U.S. heart rhythm treatment (Reuters Health) - Black patients in the U.S. with atrial fibrillation - an irregular heart rhythm - are less likely[] Retrograde inverted P waves with short PR intervals and a heart rate of 94/minute denotes to accelerated junctional rhythm. Click here for a more detailed ECG ECG 3.[] Therefore the PR interval will be short.[]

  • Multifocal Atrial Tachycardia

    Many patients are asymptomatic, however, primarily because irregular heart beats may alternate with normal heart rhythm.[] Bundle branch block with short PR interval in healthy young people prone to paroxysmal tachycardia.[] The retrograde P wave may appear before, during, or after the QRS complex; if before, the PR interval is usually short (i.e., 0.12 s).[]

  • Wolff-Parkinson-White Syndrome

    , rapid, and irregular heart rhythm).[] Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography[] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[]

  • Atrial Bigeminy

    Frequent premature beats can also be perceived as having an irregular heart rhythm (despite the underlying sinus rhythm).[] Bundle branch block with short PR interval in healthy young people prone to paroxysmal tachycardia.[] Arrhythmia Also called: Irregular heartbeat An arrhythmia is a problem with the rate or rhythm of your heartbeat.[]
