Abstract:
We describe the case of a patient with heterotopic transplantation, sinus rhythm originating from the donor heart, ventricular fibrillation of the native heart and right severe decompensation. The double rhythm was easily detected with a surface ECG and the transthoracic echocardiogram, both performed in the left conventional and in the right modified mode. The patient was successfully treated with direct current shock with quick restoration of native heart synchronization and clinical relief of symptoms.

The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...
Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
