Medical history (history) represents an important component in the diagnosis of supraventricular tachycardia (SVT). Family History Do you have relatives who suffer from palpitations or other cardiac arrhythmias? Social history Is there any evidence of psychosocial stress or strain due to your family situation? Current medical history/systemic history (somatic and psychological complaints). When did the … Supraventricular Tachycardia: Medical History
Cardiovascular System (I00-I99). Cardiac arrhythmias, unspecified Pulmonary embolism – acute occlusion of one or more pulmonary vessels. Myocardial infarction (heart attack)
The following are the major diseases or complications that may be contributed to by supraventricular tachycardia (SVT): Cardiovascular System (I00-I99) AV block and other arrhythmias. Heart failure (cardiac insufficiency) Cardiac death
A comprehensive clinical examination is the basis for selecting further diagnostic steps: Assessment of consciousness using the Glasgow Coma Scale (GCS). General physical examination – including blood pressure, pulse, body weight, height; furthermore: Inspection (viewing). Skin and the mucous membranes Neck vein congestion? Central cyanosis? (bluish discoloration of skin and central mucous membranes, e.g., tongue). … Supraventricular Tachycardia: Examination
2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification. Small blood count Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate). Electrolytes – potassium, magnesium Thyroid parameters – TSH Highly sensitive cardiac troponin T (hs-cTnT) or troponin I (hs-cTnI) … Supraventricular Tachycardia: Lab Test
Therapeutic target Initially, the achievement of a heart rate of less than 110/min. Termination of the cardiac arrhythmia Therapy recommendations Acute treatment: Hemodynamically stable: vagal maneuvers Valsalva squeeze test (synonym: Valsalva maneuver; cardioversion rate: 17-43%): Body position: backrest placed flat and both legs of the patient lifted about 45 degrees by the assistant in an … Supraventricular Tachycardia: Drug Therapy
Obligatory medical device diagnostics. Electrocardiogram (ECG; recording of myocardial electrical activity) [rate ≥ 100/min; due toDD: supraventricular tachycardia (SVT) shows a QRS complex with normal width (QRS width ≤ 120 ms); ventricular tachycardia: QRS complex > 120 msec]Note: On 12-lead ECG, ventricular tachycardia (VT) can never be reliably differentiated from supraventricular tachycardia (SVT) in the … Supraventricular Tachycardia: Diagnostic Tests
The following symptoms and complaints may occur together with supraventricular tachycardia (SVT): Leading symptoms Sudden onset of tachycardia (heartbeat too fast: >100 beats per minute). Accompanying symptoms (common in people with cardiovascular disease). Hypotension – too low blood pressure Angina pectoris – “chest tightness”; sudden onset of pain in the heart area. Vertigo (dizziness) Syncope … Supraventricular Tachycardia: Symptoms, Complaints, Signs
Pathogenesis (development of disease) Supraventricular tachycardia (SVT; atrial tachycardia) originates in the atrium or valvular plane or conduction system (atrioventricular [AV] node, His bundle). The most common trigger is intraatrial reentry (IART). Other causes include depolarizations of alternative foci. Etiology (Causes) Disease-related causes. Endocrine, nutritional, and metabolic diseases (E00-E90). Hyperthyroidism (overactive thyroid gland). Cardiovascular system … Supraventricular Tachycardia: Causes
