Vasovagal Syncope

Vasovagal syncope is the most common cause of fainting and is triggered when a person’s body reacts in an exaggerated manner to factors such as the sight of blood or extreme emotional stress. Loss of consciousness is short and is caused by a sudden drop in heart rate and blood pressure, which reduces the blood […]

Implantation Of Cardioverter Defibrillator

  What is a defibrillator?   The defibrillator (ICD) is an electronic device that constantly monitors the heart rhythm. When it detects a rapid, abnormal heart rate, it offers energy to the muscle, making the heart to return to its normal rhythm.   Why is an ICD needed?   Tachycardia and ventricular fibrillation are two […]

Sinoatrial Block

What is sinoatrial block? Sinoatrial block is a heart rhythm disorder characterized by blocking electrical impulse conduction from the SA node (the origin of the normal electrical activity) and atria (upper chambers of the heart). Normal heartbeat is controlled by electrical signals that start in the sinoatrial node.  The sinoatrial node is located at the […]

Cardiopulmonary Resuscitation

Cardiac arrest is an absolute emergency because the obstruction of the blood flow for 3-5 minutes is enough to cause irreversible brain damage. In this time, the diagnosis must be put, the gestures of resuscitation and life support insurance, followed by obtaining a spontaneous cardiac activity. In all cases, it is required the intervention of […]

  Overview of the procedure. Electrophysiology techniques that seek to define the mechanism of cardiac arrhythmias (heart rate accelerations) are entered into clinical practice for decades. These techniques involve recording local electrical activation of the heart as it exists at a time, or after trying to trigger arrhythmias by specific methods. For this study are […]

Vagal Maneuvers – Indications And Possible Complications

1. Tachycardia with narrowed QRS complex Indications: –        In order to decrease conduction velocity and to increase the refractory period at the atrioventricular node level; –        Decreased atrial refractory period; –        Decrease in frequency electrical impulse formation in the sino-atrial node. 2. Exposure of the block location in case of atrioventricular block 2: 1 Indications: […]

Ablation through radiofrequency current

The principle of the method of trans-catheter ablation consists of positioning a probe at the level of critical areas for pathological circuit and delivered energy through the probe, which can create a smooth scar, capable of interrupting the circuit. Trans-catheter radiofrequency current ablation involves the application of a current of radiofrequency (RF) catheter through a […]

Tilt Test – indications

Tilt test is a relatively easy method which proved very useful in evaluating patients with syncope. Indications for tilt test Patients with recurrent syncope or with a single syncopal episode trauma without organic heart disease or without specified etiology of syncope. Evaluation of patients in whom the etiology of syncope was precise, but in which […]

Complications and risks of the electrophysiological study

Electrophysiological studies are less traumatic than they seem to be. By using the appropriate equipment and thanks to the specialist’s skills and experience, the complications are minimal. The most common complications that can occur, regardless of the measures taken, are: 1. Bleedings at the puncture site, which are usually insignificant in the case of a […]

Life with a Pacemaker

Before implanting a pacemaker are made a few investigations to confirm the indication: recording the heart rate for 24 hours (Holter ECG); Electrophysiological study which consists in exploring ways of driving electricity to the heart using a probe that is placed in the heart. From what is made a pacemaker? One or two electric wires; […]
