What Is A Pacemaker? A pacemaker is an implantable device which is positioned typically underneath your left collarbone. It consists of a battery with a computer circuit connected to one or more pacing electrodes (electrical wires) which attach to your heart. Types of Pacemakers Single-chamber pacemaker This type of pacemaker has one lead that connects the pulse generator to one chamber of your heart. For most people, we use the single-chamber pacemaker to control heartbeat pacing by connecting the lead to your right ventricle (lower heart chamber). Depending on your symptoms and the type of pacing you need, we connect the lead to your right atrium (upper heart chamber) to stimulate the pacing in that chamber. This pacemaker helps the two chambers work together, contracting and relaxing in the proper rhythm. The contractions allow blood to flow properly from the right atrium into the right ventricle. Depending on the pacing needs of your heart, a dual-chamber device m...

What is Cardiogenic shock? Cardiogenic shock (CS) is characterized by systemic hypoperfusion due to severe depression of the cardiac index (<2.2 [L/min]/m2) and sustained systolic arterial hypotension despite an elevated filling pressure (pulmonary capillary wedge pressure. It is associated with in-hospital mortality rates >50%. Circulatory failure based on cardiac dysfunction may be caused by primary myocardial failure, most commonly secondary to acute myocardial infarction (MI), and less frequently by cardiomyopathy or myocarditis, cardiac tamponade, or critical valvular heart disease. It is also define as cardiogenic shock occurs when the heart has been damaged so much that it is unable to supply enough blood to the vital organs of the body. As a result of the failure of the heart to pump enough nutrients to the body, blood pressure falls and organs may begin to fail. What are the Causes of Cardiogenic Shock? In most scenario, a lack of oxygen to your hear...
