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

Because Lidocaine is decreasing the Ventricular Excitability which is the only source of Impulses in 3 AVB.Hence it would cause Acute heart failure....
First-degree heart block or AV (arterioventricular) block, or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds.First-degree heart block rarely causes any symptoms or problems and normally remain undiagnozed.RegardsTime is imaginary
I predict that the story will end up with telling the truth like heart to heart conversation
An artery is a pathway for the blood to travel to and from the heart. If the artery is block, the heart cannot release or receive blood, and therefore, causes heart problems.

Third-degree block, also called complete heart block, is the most serious.
Atrioventricular Dissociation (or commonly known as Complete Heart Block).
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.

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.
Detection of BBB usually takes place during a normal physical examination. The block shows up as a widening of the second heart sound.
third degree heart block
In second-degree heart block, not every impulse reaches its destination.
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.
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.
