Complete heart block is where the electrical impulses from the SA node of the heart cannot reach the ventricles along the normal pathway. Instead the atrial contract from the SA node singles and the ventricles contract from the ventricular cells

What does heart block mean?

Heart block refers to a condition where the electrical signals that control the heartbeat are partially or completely blocked as they travel through the heart. This can lead to a slowed heart rate or irregular rhythms, which may cause symptoms like fatigue, dizziness, or fainting. There are different degrees of heart block, ranging from first-degree, which is usually mild, to third-degree (complete heart block), which can be life-threatening and often requires treatment like a pacemaker.


Why lidocaine is not given in complete heart block?

Because Lidocaine is decreasing the Ventricular Excitability which is the only source of Impulses in 3 AVB.Hence it would cause Acute heart failure....


What is difference with systolic and diastolic?

SYSTOLIC: Relating to a systole or happening during a systole. But what is a systole? It is the contraction of the chambers of the heart(especially the ventricles) to drive blood into the aorta and pulmonary artery. DIASTOLIC: Relating to a diastole or happening during a diastole. But what is a diastole ? The widening of the chambers of the heart between two contractions when the chambers fill with blood is called a diastole.

What does a complete left bundle branch block mean?

A complete left bundle branch block (LBBB) occurs when there is a blockage in the electrical pathway (bundle branch) that carries signals to the left side of the heart. This can cause a delay in the electrical signals reaching the left ventricle, leading to changes in the appearance of the ECG waveforms. It may indicate an underlying heart condition and should be evaluated by a healthcare provider.


What is the interruption of these impulses in the heart's conduction system?

Interruption of the impulses in the heart's conduction system is known as heart block. Heart block may be caused by scar tissue from a heart attack, among other things.
