Likely normal: Rsr', pronounced 'r s r-prime' can be a normal finding in leads v1 and v2. This pattern is often found in young healthy people. An rsr' with widening of the qrs and characteristic findings in other leads is due to a right bundle branch block. This is when the electrical pathway to the right ventricle is slower than the pathway to the left venricle (typically several milliseconds).

Right Bundle: It's ekg notation for the shape of the waveform, and it means there's either block or delay in one of the heart's 3 "wires" (they're not really wires) that conduct the electrical impulse to the lower chambers. It does not, generally, mean increased risk of death or problems unless other circumstances are present.
