Abstract:
The authors analyze the number and type of electrophysiologic procedures (diagnostic and ablation, and implantation of defibrillators and biventricular pacemakers with defibrillator backup) that were performed during 2009 in all Portuguese electrophysiology centers. A total of 2669 diagnostic electrophysiologic procedures were performed during the year, of which 62% were followed by ablation, amounting to 1668 ablations. The authors describe the type of ablations performed by the various centers, and analyze the distribution and type of ablation procedures in the light of recent data from published international studies. A total of 1089 ICDs were implanted during 2009, and the authors also describe the type of devices employed and comment on these data bearing in mind recent published data.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
