  1. Arrhythmias

    The normal heart beats regularly at 60–100 beats per min (bpm), which is controlled by the sinoatrial (SA) node located in the right atrium. Tachycardia describes a heart that beats more rapidly (>100 bpm). Bradycardia describes a situation where the heart beats more slowly (<60 bpm). Electrical signals generated in the SA node travel through a conduction pathway in the wall of the atria (causing atrial contraction) before reaching and depolarising the AV node.

  2. Neurotransmitters

    Synaptic transmission relies on local synthesis, and release of neurotransmitter molecules at the synapse, binding of the neurotransmitter to its cognate post-synaptic receptor(s) and inactivation/removal of the neurotransmitter from the synaptic space to terminate the activation.
