The P wave represents atrial depolarization (they contract). In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
A low voltage EKG means the amplitude of the QRS waves on the EKG are lower than would be expected. COPD, obesity, and pericardial effusions can cause low EKG voltages, amongst other causes.
A murmur is heard by a clinician through a stethoscope and cannot be detected on EKG. However, an EKG reading may occasionally suggest a possible cause for the murmur. Most likely your clinician will be able to determine the cause of the murmur based on clinical grounds, or with the aid of an echocardiogram.
It's a wandering thought from no apparent cause.
