2nd order laboratory parameters – depending on the results of the history, physical examination, etc. – 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) – to exclude … Ventricular Tachycardia: Lab Test
Therapeutic target To correct the life-threatening cardiac arrhythmia, as it is considered a risk factor for sudden cardiac death. Therapy recommendations Stable hemodynamic situation: Attempt therapy with amiodarone (first-line agent); this may facilitate cardioversion and/or prevent recurrence of ventricular tachycardia or fibrillation; not in shock or hyperthyroidism! If necessary, also ajmaline Unstable hemodynamic situation* : … Ventricular Tachycardia: Drug Therapy
Medical history (history) is an important component in the diagnosis of ventricular tachycardia (VT). Family History Do you have relatives who suffer from palpitations or other cardiac arrhythmias? Social history Current medical history/systemic history (somatic and psychological complaints). When did the palpitations first occur? When did the palpitations last occur? How often does the palpitations … Ventricular Tachycardia: Medical History
Cardiovascular System (I00-I99). Atrioventricular re-entrant tachycardia (AVRT) – belongs to paroxysmal supraventricular tachycardia and results in typical seizure-like episodes with tachycardia (heartbeat too fast: >100 beats per minute), dizziness, and possibly signs of acute heart failure (heart failure) Extrasystoles (heart stutter) – heartbeat that occurs outside the physiological heart rhythm. Ventricular flutter – life-threatening cardiac … Ventricular Tachycardia: Or something else? Differential Diagnosis
Electrical cardioversion (synonyms: electrocardioversion; DC cardioversion) is a therapeutic cardiology procedure to restore sinus rhythm (regular heart rhythm) to an existing arrhythmia. Defibrillators are used to establish the correct heart rhythm in a patient with the help of electrocardioversion. A defibrillator is used to apply an electric current to the heart at defined points in … Electrical Cardioversion
The following are the major diseases or complications that may be contributed to by ventricular tachycardia (VT):Cardiovascular system (I00-I99). Ventricular fibrillation (VF). Sudden cardiac death (PHT) Jumping to a different heart rhythm Further “Electrical storm” (= occurrence of ≥ 3 non-self-limited episodes of ventricular fibrillation in 24 h).
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). … Ventricular Tachycardia: Examination
Obligatory medical device diagnostics. Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) [Ventricular tachycardia (VT): wide-complex tachycardia (heart rate > 120/min; QRS complex: duration ≥ 120 ms); Monomorphic VT – in ischemic cardiomyopathy/cardiomyopathy with reduced blood flow to the myocardium and after myocardial infarction/heart attack; dilated cardiomyopathy/diseased dilatation of the myocardium, especially … Ventricular Tachycardia: Diagnostic Tests
The following symptoms and complaints may indicate ventricular tachycardia (VT): Leading symptoms Tachycardia (heartbeat too fast: > 100 beats per minute) [heart chambers (ventricles) produce a heartbeat that is at least 100 beats per minute independent of the sinus node itself (tachycardia)] Vertigo (dizziness) Dyspnea (shortness of breath) Syncope (momentary loss of consciousness) to persistent … Ventricular Tachycardia: Symptoms, Complaints, Signs
Pathogenesis (development of disease) Ventricular tachycardia (VT) is a cardiac arrhythmia with increased heart rate of >100 beats/min originating from the ventricles (heart chambers). There is a uniform (monomorphic) or variable (polymorphic) electrical activation of the myocardium (heart muscle). This usually arises there from a reentry mechanism (circular excitation). VTs usually arise from structural heart … Ventricular Tachycardia: Causes
Immediately call 911! (Call 112) Conventional nonsurgical therapy methods Electrocardioversion: electrocardioversion is the treatment of tachycardic (high-frequency) arrhythmias with direct current through the chest. This method is performed for ventricular tachycardia in patients with severe compromised health. Catheter ablation for idiopathic ventricular tachycardia (VT) – VT in which a structural anatomic cause has been ruled … Ventricular Tachycardia: Therapy
