Increased blood flow: Respiratory activity influences venous return to the heart. Briefly, increasing the rate and depth of respiration promotes venous return and therefore enhances cardiac output. Non-typical respiratory activity such as being on positive pressure ventilation or doing a forced expiration against a closed glottis (valsalva maneuver) impedes and therefore reduces venous return and cardiac output.

Bad stuff: Your heart rhythm is normally a carefully coordinated event that has a natural progression electrically to create an effective forceful heart beat. When you have 3rd degree block, it's completely discordant (ie nothing is working together) . When the different parts of the heart are doing their own thing without communicating properly, it's life threatening and requires a pacemaker

Take your pulse: At some point during peak exercise stop and take your pulse. Count the heartbeats over 10 seconds (and multiply by 6) or 15 seconds (and multiply by 4). This will give you beats per minute, which are the units to measure heart rate.
