It is quite possible to have the p without the qrs as in the case of my son.
His pacer was atrial demand. When he lost the electrical response from the

Very rare. The cardiology department at Childrens Hospital of Philadelphia
agrees with the concept that atrial repolarization carries to little current to
show up on the tracing.
