250 Possible Causes for Bradycardia, Prolonged PR Interval

  • Second Degree Atrioventricular Block

    Abstract We present an example of bradycardia-dependent aberrancy in the left posterior fascicle in the presence of type I second-degree atrioventricular block occurring in[] This case demonstrates the need for caution and interval cardiac testing when adding LCM to other AEDs known to prolong the PR interval.[] An attempt was made to explain the mechanism for such apparent bradycardia-dependent atrioventricular block by using the concepts of periodic increases in vagal tone due to[]

  • AV Block Mobitz I

    (C) Bradycardia with normal heart rate intervals at a rate of 55 after Mobitz type II AV block. (D) Mobitz type II AV block reappeared when the ureterus was repaired.[] The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs. Mobitz type 2 block has constant PR intervals before blocks occur.[] Requiring similar P wave morphology when assessing an arrhythmia for AV block eliminates other potential causes of bradycardia such as wandering pacemaker, sinus pauses, and[]

  • AV Block Mobitz II

    (C) Bradycardia with normal heart rate intervals at a rate of 55 after Mobitz type II AV block. (D) Mobitz type II AV block reappeared when the ureterus was repaired.[] Commonly used terminology includes: First degree AV block – Delayed conduction from the atrium to the ventricle (defined as a prolonged PR interval of 200 milliseconds) without[] Every-other-P wave conducts – as determined by the presence of a fixed ( albeit prolonged ) PR interval preceding each QRS complex on the tracing.[]

  • Sinoatrial Block

    The purpose of the present article is to show that the patients have apparent bradycardia-dependent SA block, namely, not true bradycardia-dependent SA block.[] This is different than a first-degree atrioventricular, or AV, block, which shows a prolonged PR interval.[] Mobitz Type 1 (Wenckebach) • Gradual prolongation of PR interval until nonconducted p wave • RP-PR reciprocity • Lengthening of the PR interval at progressively shorter decrements[]

  • Hyperkalemia

    The significance of sever bradycardia can vary widely.[] ., prolonged PR interval, wide QRS complex) as an alternative to 10 units of short acting insulin.[] , prolonged PR interval, prolonged QRS interval, loss of P wave, sine waves and finally ventricular fibrillation (see ECG guideline for normal values for age) ECG CHANGES[]

  • Verapamil

    […] disease, and the number and types of other medications, are further predictors of marked bradycardia with hypotension.[] Prolongation of PR intervals by G coadministration was borderline significant; an increase above 350 ms occurred in two individuals during the G period.[] These patients should be carefully monitored for abnormal prolongation of the PR interval or other signs of overdosage (see OVERDOSAGE ).[]

  • Propranolol

    Interestingly, among the reported cases of patients with sofosbuvir and amiodarone related bradycardia, some of them were also treated with propranolol.[] [ECG], but manually calculated to be 440 ms]), no cardiac abnormalities (PR interval: 104 ms, QRS duration: 78 ms), and generalised anxiety disorder (ICD-10-CM Diagnosis[] Propranolol can have potentially serious adverse side effects, including bradycardia, hypotension, and hypoglycemia.[]

  • Accidental Hypothermia

    Abstract A 35-year-old schizophrenic patient was admitted to the Coronary Care Unit with shock, bradycardia and ST-T changes mimicking acute myocardial infarction.[] As temperatures continue to drop, the ECG will demonstrate prolonged intervals: PR, followed by QRS and then QTc.[] Additional findings included atrial fibrillation, severe sinus bradycardia, and prominent J (Osborn) waves.[]

  • Sick Sinus Syndrome

    Abstract Bradycardia-dependent block or activation delay of the atrial tissue has not been documented in the literature.[] On postnatal electrocardiography, there was junctional escape rhythm due to profound sinus bradycardia, leading us to consider sick sinus syndrome.[] People suffering from bradycardia may present with palpitations, exercise intolerance and fainting.[]

  • Procainamide

    Confusion, seizures, hypotension, bradycardia, reflex tachycardia, ventricular dysrhythmias, AV blocks, asystole, widening of PR, QRS, and Q-T intervals, N/V.[] BACKGROUND: Procainamide is known to prolong PR, QRS, and QTc intervals in adults and is utilized to unmask the distinct electrocardiographic signatures, including right bundle[] Torsades de Pointes (associated with high levels of procainamide and/or NAPA; secondary to prolonged QT interval ) heart block prolongation of PR, QRS, QT intervals (up to 50%) bradycardia[]
