  • Hypertrophic Cardiomyopathy

    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] interval of 120 to 180 ms, but when the PR interval is shorter, a very short AV delay (50 to 60 ms) is frequently required for complete ventricular capture. 183 This often[doi.org] […] in women Premature ventricular beats or more severe ventricular arrhythmia Supraventricular tachycardia, atrial flutter, or atrial fibrillation Ventricular preexcitation: short[doi.org]

  • Myocardial Infarction

    Myocardial infarction, commonly referred to as heart attack, is a condition characterized by necrosis of the heart muscles due to development of ischemia that stays on for prolonged periods. Such a condition develops when the heart does not receive oxygen and blood due to blockage in the coronary arteries.[…][symptoma.com]

  • Acute Myocardial Infarction

    We herein report the case of a 25-year-old Japanese woman with left-main-trunk acute myocardial infarction (LMT-AMI). She had cardiogenic shock, so emergency percutaneous intervention was performed. Intravascular ultrasound of LMT-AMI showed that the three-layered structure of the intima, tunica media, and[…][ncbi.nlm.nih.gov]

  • Wolff-Parkinson-White Syndrome

    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[ncbi.nlm.nih.gov] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[ncbi.nlm.nih.gov] Elective cardioversion restored sinus rhythm, and the ECG showed a wide QRS complex, short PR interval, and delta wave, indicating the presence of an accessory pathway and[ncbi.nlm.nih.gov]

  • Preexcitation Syndrome

    PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[medical-dictionary.thefreedictionary.com] The classic electrocardiogram in Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval and prolonged QRS duration in the presence of sinus rhythm with[ncbi.nlm.nih.gov] However the main basis for this diagnosis is the ECG which associates short PR interval and widening of QRS complex with a delta wave.[ncbi.nlm.nih.gov]

  • Graves Disease

    Background The association of hyperthyroidism with renal disease is very rare and the importance of timely clinical recognition cannot be overemphasized.
