The diagnostic value of the head-up tilt test (HUTT) in discovering vasovagal syndrome depends on the pre-test probability. An accurate anamnesis and clinical examination screens the patients indicated for the HUTT. In patients with unexplained syncope, the R-test is an alternative procedure to discover its cause. In our study, we evaluated the diagnostic significance of the HUTT in a group of 211 patients and of the R-test in a subgroup of 45 patients with negative HUTT results and with negative traditional Holter ECG monitoring (24 hr).

Paroxysmal supraventricular tachycardia (PSVT) defines a group of cardiac arrhythmias where the underlying mechanism is dependent upon structures at or above the level of the atrioventricular node. The recent PRE-EMPT study retrospectively evaluated health records of over 4.2 million people in the USA, estimating PSVT incidence at 73/100,000, and national prevalence at 168/100,000 (translating into […]

Several closely regulated ion channels are involved in the various phases of the myocardial action potential (phases 0–4) (Figure 1).1 In the absence of neuroendocrine and other regulatory signals, the pacing rate of the sinoatrial node is 100 beats per minute (bpm). However, heart rate is not fixed, and varies along with cardiac output in order […]
Supraventricular Tachycardia: Electrocardiogram Diagnosis and Clinical Management for the Non-electrophysiologist
European Journal of Arrhythmia & Electrophysiology. 2021;7(1):Online ahead of journal publication.
Supraventricular tachycardia (SVT) occurs with a prevalence of 2–3/1,000 in the general population and is characterised by atrial rates >100 beats per minute (bpm) at rest. Per definition, SVT originates in the atria or atrioventricular (AV) node tissue above the His bundle.1,2 Diagnosis and clinical management of SVT have been the focus of recent European Society […]
