427 Possible Causes for Sinus Bradycardia, Supraventricular Tachycardia

  • Sick Sinus Syndrome

    Types of sick sinus syndrome Sinus bradycardia A normal heart rate is considered to be from 60 to 100 beats per minute.[] Exercise seldom provokes tachycardia in patients with paroxysmal supraventricular tachycardia (PSVT).[] Types of tachycardias include atrial fibrillation, atrial flutter/tachycardia, and supraventricular tachycardia bradycardia-tachycardia, which causes alternating slow and[]

  • Cardiomyopathy

    Cardiac manifestations include pericarditis, supraventricular tachycardias, and heart block. [60] Myocardial involvement/systolic dysfunction has also been described, although[] […] findings may include the following: ST-T wave abnormalities and LVH (common) Axis deviation (right or left) Conduction abnormalities (P-R prolongation, bundle-branch block) Sinus[] Collagen remodeling and changes in LV function during development and recovery from supraventricular tachycardia. Am J Physiol, 261 (1991), pp. 308-318 [70] F.G.[]

  • 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[] tachycardia following old myocardial infarction Supraventricular tachycardia post old mi Clinical Information Documented history of previous myocardial infarction (mi), typically[] 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[]

  • Acute Myocardial Infarction

    Electrocardiographic changes include ST segment elevation, onset of sinus tachycardia (by adrenergic discharge), malignant ventricular arrhythmias, extreme bradycardia, and[] The pulse may be irregular because of ventricular ectopy, an accelerated idioventricular rhythm, ventricular tachycardia, atrial fibrillation or flutter, or other supraventricular[] , atrial fibrillation or flutter, or other supraventricular arrhythmias; bradyarrhythmias may be present In general, the patient's blood pressure is initially elevated because[]

  • Acute Atrial Infarction

    TABLE 1 Atrial infarction complications Complication Incidence Rhythm disturbances 61%–74% Supraventricular tachycardia Atrial fibrillation Wandering atrial pacemaker Sinus[] After coronary angiography, the patient had chest pain associated with hypotension, sinus bradycardia, periods of complete atrioventricular block, and one episode of ventricular[] Sinus tachycardia may be due to pain, anxiety, or drugs. Atrial fibrillation and other supraventricular tachycardias may also occur.[]

  • 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[] Syncope may be caused by very fast heart rhythms — tachycardias — such as in supraventricular tachycardia (SVT) or ventricular tachycardia.[] Upon his admission, an electrocardiogram showed sinus bradycardia, and computed tomography of the neck with contrast showed a large parapharyngeal mass involving the prestyloid[]

  • Digitalis Toxicity

    Digitalis is a cardiac glycoside frequently used in the therapy of chronic heart failure, reentrant supraventricular tachycardia and atrial fibrillation.[] ., sinus bradycardia, atrioventricular block, nonparoxysmal atrioventricular junctional tachycardia, and ventricular tachycardia.[] bradycardia Magnesium sulfate may terminate dysrhythmias, but is contraindicated in the setting of bradycardia or AV block and should be used cautiously in patients with[]

  • Accidental Hypothermia

    Additional findings included atrial fibrillation, severe sinus bradycardia, and prominent J (Osborn) waves.[] Sinus bradycardia was observed in 52.5% of the patients.[] Her cardiac rhythm showed sinus bradycardia. The patient’s airway was secured by rapid sequence intubation with 2 mg midazolam, and 30 mg rocuronium.[]

  • Cardiac Tamponade

    Case A 70-year-old physically active female with a history of paroxysmal supraventricular tachycardia on sotalol 80mg twice daily presented to the emergency room with a brief[]

  • Atrioventricular Junctional Rhythm

    […] result of this treatment is the lack of supraventricular tachycardia (SVT) inducibility with or without single atrioventricular (AV) nodal echo beats.[] sinus syndrome or in patients who have significant bradycardia that allows the AV nodal region to determine the heart rate.[] Patients with supraventricular tachycardia presenting with aborted sudden death: incidence, mechanism and long-term follow-up.[]
