113 Possible Causes for Short PR Interval, Sinus Bradycardia

  • Hypertrophic Cardiomyopathy

    ECG: Findings also may include right or left axis deviation, conduction abnormalities, sinus bradycardia with ectopic atrial rhythm and atrial enlargement.[patient.info] PR interval ( First-degree (PR 0.21 s, not shortening with hyperventilation), second-degree, or third-degree atrioventricular block To assess whether the changing pattern[doi.org] bradycardia with ectopic atrial rhythm, and atrial enlargement.[symptoma.com]

  • Myocardial Infarction

    We describe a 41-year-old man who presented with steep down-sloping ST-segment elevation, paroxysmal ventricular tachycardia, severe sinus bradycardia, and intermittent complete[ncbi.nlm.nih.gov] Sweating Tachycardia Vomiting and sinus bradycardia– this may occur as a result of excessive vagal stimulation, which is most common in inferior MI Nausea and vomiting may[almostadoctor.co.uk] Pacing in STEMI: Recommendation Class I Temporary pacing is indicated for symptomatic bradyarrhythmias unresponsive to medical treatment. ( Level of Evidence: C ) Sinus bradycardia[doi.org]

  • Acute Myocardial Infarction

    Electrocardiographic changes include ST segment elevation, onset of sinus tachycardia (by adrenergic discharge), malignant ventricular arrhythmias, extreme bradycardia, and[f1000research.com]

  • Atrioventricular Junctional Rhythm

    sinus syndrome or in patients who have significant bradycardia that allows the AV nodal region to determine the heart rate.[emedicine.com] 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.[metealpaslan.com] Short PR interval ( 120 ms) indicates a junctional rather than atrial focus.[litfl.com]

  • Atrial Tachyarrhythmia with Short PR Interval

    Sinus bradycardia · Sick sinus syndrome Heart block : Sinoatrial · AV ( 1 , 2 , 3 ) · Intraventricular ( Bundle branch / Right / Left, Left anterior fascicular / Left posterior[dictionnaire.sensagent.leparisien.fr] Five additional family members had short PR intervals with normal QRS, and eight other family members had borderline short PR intervals.[ncbi.nlm.nih.gov] Sinus Bradycardia As was the case with sinus tachycardia, sinus bradycardia means that the SA node is driving the heart, but now it is slower than the normal range.[courses.kcumb.edu]

  • Syncope

    During her hospitalization for tapering of AEDs and 24-hour EEG monitoring, the patient developed a seizure followed by sinus bradycardia and an 18-second sinus pause, resulting[ncbi.nlm.nih.gov] So here goes: W is Wolff-Parkinson-White syndrome – look for a short PR interval or delta wave: O is obstructed AV pathway – look for 2nd or 3rd degree block: or axis deviation[resus.me] Upon his admission, an electrocardiogram showed sinus bradycardia, and computed tomography of the neck with contrast showed a large parapharyngeal mass involving the prestyloid[ncbi.nlm.nih.gov]

  • Atrial Bigeminy

    bradycardia with ventricular rates of 38-45 beats/min and the ectopic P waves were visible on only one of the ECG channels); 3. paroxysms of atrial fibrillation initiated[ncbi.nlm.nih.gov] Juls Registered Nurse Doesn't a flipped p with a short pr interval mean a junctional foci? So junctional bijemini?[app.figure1.com] Bundle branch block with short PR interval in healthy young people prone to paroxysmal tachycardia.[books.google.com]

  • Atrioventricular Dissociation

    We present a case of a young man with meningococcal meningitis and various asymptomatic temporary ECG abnormalities, including sinus bradycardia, atrioventricular dissociation[ncbi.nlm.nih.gov] Bundle branch block with short PR interval in healthy young people prone to paroxysmal tachycardia.[books.google.com] Interference AV dissociation is initiated by slowing of the sinus node due to sinus bradycardia or sinus arrest, thereby allowing an independent subsidiary pacemaker in the[emedicine.medscape.com]

  • Enhanced Vagal Tone

Few with CHB require it Persistent hypotension and RVMI needs it often.[drsvenkatesan.com] PR Interval 0.12 s (see Wolff Parkinson White Syndrome (WPW)): The differential for a PR interval less than 0.12 s is short and largely limited to the diagnosis of an accessory[clinicaladvisor.com] The differential of a junctional rhythm at lower rates includes a normal response to increased vagal tone during sleep and sinus bradycardia, inappropriate sinus bradycardia[misc.medscape.com]
