[ECG pearl: Valsalva maneuver terminated ventricular tachycardia].

Összefoglaló. Egy 78 éves férfi széles-QRS-tachycardiás esetét mutatjuk be. A betegnél a pitvar-kamrai disszociáció igazolta a ritmuszavar kamrai eredetét, amelyet a Valsalva-manőverrel több alkalommal is átmenetileg meg lehetett szüntetni.

[ECG pearl: tonic-clonic seizure detected by implantable loop recorder].

A 52-year-old woman is presented with repetitive transient loss of consciousness. Implantable loop recorder (ILR) recorded muscle artifacts during the generalized tonic-clonic seizures. Seizure was diagnosed and antiepileptic drug was started.

[Role of implantable loop recorder in the clinical diagnosis of syncope: results of the introduction of an effective diagnostic tool].

Introduction: Extension of electrocardiographic monitoring via loop recorder implantation may increase the diagnostic yield of syncope work-up.

Aim: In this retrospective observational study, the authors wanted to evaluate the diagnostic performance of implantable loop recorder in the everyday clinical practice.

Method: The authors analyzed the electronically stored data of all patients who underwent loop recorder implantation between 2005 and 2014 in their cardiology department because of recurrent syncope of undetermined origin.

[A new ECG marker of anterior acute myocardial infarction].

ST-segment elevation is the hallmark of acute transmural myocardial ischemia caused by acute occlusion of a coronary artery. ST-segment elevation is the major criterion for the patients with chest pain to immediate reperfusion therapy. Despite its clinical importance, the mechanism of ST-elevation remains unclear.
