The leads are: - Atrial lead at the right appendage - Right ventricular lead at the apex - Left ventricular lead through the coronary sinus. [7] CRT requires the placement of an electrical device for biventricular pacing, along with placement of (at least) two pacing leads, to facilitate stable left ventricular and right ventricular pacing.
Dextrocardia (from Latin dextro 'right hand side' and Greek kardia 'heart') is a rare congenital condition in which the apex of the heart is located on the right side of the body, rather than the more typical placement towards the left. [1]
Normal 12-lead ECG A 12-lead ECG of a 26-year-old male with an incomplete right bundle branch block (RBBB). The overall goal of performing an ECG is to obtain information about the electrical functioning of the heart.
A normal chest X-ray after placement of an ICD, showing the ICD generator in the upper left chest and the ICD lead in the right ventricle of the heart. Note the 2 opaque coils along the ICD lead. The process of implantation of an ICD system is similar to implantation of an artificial pacemaker. In fact, ICDs are composed of an ICD generator and ...
The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. The hexaxial reference system, better known as the Cabrera system, is a convention to present the extremity leads of the 12 lead electrocardiogram, [1] that provides an illustrative logical sequence that helps interpretation of the ECG, especially to determine the heart's ...
Occasionally the right side is preferred for certain patients or other specific reasons. In contrast to a transvenous ICD, the pulse generator is implanted on the left side of the chest next to the rib cage, just under the arm, and the lead is implanted just under the skin above the breastbone.
November retail sales grew at a faster pace than Wall Street analysts had expected, reflecting continued resilience in the American consumer and indicating that the holiday shopping season in the ...
Lead II — This axis goes from the right arm to the left leg, with the negative electrode on the shoulder and the positive one on the leg. This results in a +60 degree angle of orientation. [4] = Lead III — This axis goes from the left shoulder (negative electrode) to the right or left leg (positive electrode). This results in a +120 degree ...
