The signals from the sinoatrial node reach the ventriclesLower chambers of the heart through the atrioventricularRelating to the atrium (upper thin walled chambers of the heart) and the ventricle (lower thick walled chambers of the heart) node via the bundle of Hismain conduction fibre group reaching the ventriclesLower chambers of the heart from the atrioventricularRelating to the atrium (upper thin walled chambers of the heart) and the ventricle (lower thick walled chambers of the heart) node and its branches. The right bundle branch taking signals to the right ventricleThe lower thick walled chambers of the heart (left and right) which receive blood from the atriumUpper thin walled chambers of the heart (left and right). They receive the blood returning to the heart and pump out into the body can often have a conduction delay and the manifestation on ECGElectrocardiogram is called right bundle branch block (RBBBright bundle branch block). It has a characteristic pattern on the ECGElectrocardiogram with an rSR’ pattern in the lead V1. Right bundle branch block can exist in the absence of any other significant heart disease and may not do much harm by itself. Right ventricular conduction delay can also be there in conditions in which the right ventricleThe lower thick walled chambers of the heart (left and right) which receive blood from the atriumUpper thin walled chambers of the heart (left and right).
