Study Notes
Cardiology
- Cardiology is the medical specialty that deals with disorders of the heart and cardiovascular system.
- The medical term for doctors who specialize in the field of cardiology is cardiologists.
Cardiothoracic Surgery
- Cardiothoracic surgeons are physicians who specialize in cardiac surgery.
Disorders in Cardiology
- Examples of disorders that fall under the field of cardiology include heart failure, coronary artery disease, and arrhythmias.

Cardiologist vs Pediatric Cardiologist
- A cardiologist specializes in the diagnosis and treatment of heart disorders in adults.
- A pediatric cardiologist specializes in the diagnosis and treatment of heart disorders in children.
Electrophysiology
- Electrophysiology in the context of cardiology is the study of the electrical properties of the heart and the diagnosis and treatment of arrhythmias.
Neuromuscular Junction
- Acetylcholine is the neurotransmitter released at the neuromuscular junction.
- The enzyme that breaks down acetylcholine at the neuromuscular junction is acetylcholinesterase.
- The type of muscle fibers primarily involved in the neuromuscular junction are skeletal muscle fibers.
- The protein that allows for the fusion of synaptic vesicles with the presynaptic membrane at the neuromuscular junction is called VAMP (vesicle-associated membrane protein).
- The receptor on the motor end plate that binds to acetylcholine is the nicotinic acetylcholine receptor.
- The protein that anchors the motor end plate to the sarcolemma of the muscle fiber is called dystrophin.
