No, damage to the AV node causes total heart block, in which signals from the atria fail to reach the ventricles and the ventricles beat at their own intrinsic rhythm of 20 to 40 bpm.
Are you sure you mean right to left atrium (SA block) or do you mean AV block. If SA block the node at the junction is blocked a person will feel light headed and the secondary node will have to keep the heart pace up. The SA node is the primary pacemaker. If it is an AV block the signal will not be transmitted to either ventricle and it too will cause the heart to slow or a beat to be dropped.
In a Cardiac condition known as heart block, there is an interruption in the message from the SA node to the AV node. The interruption can occur in varying degrees.
heart block
more than 90 beats per minute

Heart blocks slows impulse and lengthens the QRS complex of ECG; over all lowers the pulse
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
If the atrial conduction system (the SA node and bachmann bundles) and the ventricular conduction system (the AV node and purkinje system) are completely separated, third degree heart block develops. In this case, the SA node will continue to depolarize the atria at its own intrinsic rate and the ventricles will be depolarized by a focus either in the AV node or in the ventricles.
Pacemaker The heart's natural pacemaker is the sinoatrial (SA) node. The SA node sends an electrical impulse through both atria, pausing at the atrioventricular (AV) node, which is a small mass of cardiac muscle. To restore normal rhythm in the case of a block, an artificial cardiac pacemaker can be implanted in the chest.
if you eat too much heavy things in like 3 seconds and then it just goes strait down to your heart to attack i then it suddenly blocks your heart from pumping blood i know that because i happened to me last year
