AV Nodal Re-Entrant Tachycardia: Or something else? Differential Diagnosis

Cardiovascular System (I00-I99). Atrioventricular re-entrant tachycardia through an accessory pathway (AVRT) – supraventricular arrhythmia resulting in a circular excitation between the atrium and ventricle through an accessory pathway. Adenosine-sensitive ectopic atrial tachycardia. Sinus tachycardia (heartbeat too fast: > 100 beats per minute). Ventricular tachycardia – cardiac arrhythmia with too fast heartbeat, originating from the ventricles. … AV Nodal Re-Entrant Tachycardia: Or something else? Differential Diagnosis

Heart Pacemaker

A pacemaker (HSM; Schrittmacher, SM) or pacemaker (PM) is a generator used in various cardiac diseases to correct the underlying cardiac arrhythmias. The functions of a pacemaker are stimulation (delivery of an electrical impulse, on demand) and sensing (perception) of intrinsic actions. At initial implantation, the average pacemaker patient is about 78 years old; about … Heart Pacemaker

AV Nodal Re-Entrant Tachycardia: Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps: General physical examination – including blood pressure, pulse, body weight, height; furthermore: Inspection (viewing). Skin and the mucous membranes Neck vein congestion? Abdomen (abdomen) Shape of the abdomen? Skin color? Skin texture? Efflorescences (skin changes)? Pulsations? Bowel movements? Visible vessels? Scars? Hernias (fractures)? … AV Nodal Re-Entrant Tachycardia: Examination

AV Nodal Re-Entrant Tachycardia: Lab Test

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) – for suspected … AV Nodal Re-Entrant Tachycardia: Lab Test

AV Nodal Re-Entrant Tachycardia: Diagnostic Tests

Obligatory medical device diagnostics. Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – indicates the conduction of excitation of the heart [typical AVNRT: regular narrow complex tachycardia that can reach frequencies > 200/min; in sinus rhythm, the ECG usually shows an unremarkable picture]. Optional medical device diagnostics – depending on the results … AV Nodal Re-Entrant Tachycardia: Diagnostic Tests

AV Nodal Re-Entrant Tachycardia: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate AV nodal reentrant tachycardia (AVNRT): Leading symptoms Tachycardia (heartbeat too fast: > 100 beats per minute) – sudden onset of regular, usually rapid palpitations (heart rate: 160-250/min). Syncope (brief loss of consciousness). Palpitations (heart palpitations), often accompanied by feelings of anxiety. Heart failure (cardiac insufficiency) Hypotension (low blood … AV Nodal Re-Entrant Tachycardia: Symptoms, Complaints, Signs

AV Nodal Re-Entrant Tachycardia: Causes

Pathogenesis (development of disease) AV nodal re-entrant tachycardia (AVRT; acceleration of heart rate to 160-250 beats per minute due to a short-circuit connection between the atria and ventricles bypassing the AV node/other physiologic pacemaker besides the sinoatrial node) can be further subdivided based on the presence of preexcitation syndrome (premature excitation of the ventricle via … AV Nodal Re-Entrant Tachycardia: Causes

AV Nodal Re-Entrant Tachycardia: Therapy

Conventional nonsurgical therapies A vagal maneuver refers to irritation of the vagus nerve, usually in the neck at the arteries next to which the nerve runs. Pressure on these points can stop a seizure in circa 80% of cases (performed after training by your physician). Surgical therapy Catheter ablation (ablation (Lat. ablatio “ablation, detachment”) of … AV Nodal Re-Entrant Tachycardia: Therapy
