This prevents tetanus from occurring and ensures that each contraction is followed by enough time to allow the heart chamber to refill with blood before the next contraction. Previous Cardiac Conduction Next Electrocardiogram parabench attachmentsWebThis occurs when a muscle's motor unit is stimulated by multiple impulses at a sufficiently high frequency. Each stimulus causes a twitch. If stimuli are delivered slowly enough, the tension in the muscle will relax between successive twitches. If stimuli are delivered at high frequency, the twitches will overlap, resulting in tetanic contraction. parabens backgroundWebAs a result, cardiac muscle tissue cannot undergo tetanus (sustained contraction).
