Oct 8, 2024 · A review of the different types of supraventricular tachycardia (SVT) with a focus on AV-nodal re-entry tachycardia (AVNRT).

Nov 10, 2022 · Supraventricular tachycardia (SVT) is a rapid heart rhythm originating at or above the AV node. SV rhythm rates are above 100 beats per minute and are typically 150-250 bpm. SVT is a common pediatric rhythm problem.

Mar 17, 2025 · Supraventricular tachycardias are characterized on the EKG as regular tachycardias with narrow QRS complexes and high heart rate.

Jan 5, 2025 · SVT differentials & general approach. SVT basics. Speed limits; Differential diagnosis based on ECG. 1) if irregular; 2) if more P's than QRS's; 3) if undetectable P-waves; 4) if P's before QRS's; 5) if P's after QRS's; Additional observational tests. Lewis lead ECG; Telemetry: initiation, rate trending; Echocardiography for atrial flutter

Subtypes of SVT can often be distinguished by their electrocardiogram (ECG) characteristics. Most have a narrow QRS complex , although, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular tachycardia (VT).

Supraventricular tachycardia (SVT) is a common cause of hospital admissions and can cause significant patient discomfort and distress. The most common SVTs include atrioventricular nodal re-entrant tachycardia, atrioventricular re-entrant tachycardia and atrial tachycardia.

May 2, 2022 · Supraventricular Tachycardia is a category rather than specific rhythm. SVTs are tachycardic rhythms which originate above the ventricles. Cardiac monitor capture of an EKG / ECG tracing of a Supraventricular Tachycardia with …

Dec 7, 2021 · Medical history is significant for hyperthyroidism. Vital signs are significant for a blood pressure of 135/95 mmHg and a pulse of 155/min. An electrocardiogram is performed that shows a narrow QRS-complex tachyarrhythmia. Carotid sinus massage is performed and her symptoms do not improve.

Aug 7, 2023 · Common diagnostic steps include obtaining the patient's history and a 12-lead ECG to identify the type of SVT. The paroxysmal nature of SVTs means that continuous recording with a Holter monitor is often needed to confirm the diagnosis; in some cases, invasive electrophysiological studies (EP studies) may also be indicated.

Nov 8, 2021 · Supraventricular tachycardia (SVT) occurs when the heart rhythm occurs as a result of electrical impulses initiated above the ventricles at a rate of 150 - 250 bpm or more. What will remain will be a normal appearing and measuring QRS complex depolarizing at a rapid rate.
