The 16 pages that link to Cardiac action potential, each with the reason it gives.

• Action potentialBroader topic: Its prolonged phases differ from the brief spikes typical of many neurons.

• ElectrocardiographyBroader topic: These cellular voltage changes generate the electrical currents recorded at the body surface.

• HyperkalemiaRelated: Elevated extracellular potassium changes cardiac cell excitability and conduction.

• Cardiac conduction systemRelated: Action potentials are the electrical signals generated and transmitted by this tissue.

• Cardiac muscleRelated: Its prolonged plateau helps sustain contraction and prevents rapid repeated contractions.

• ElectrocardiogramRelated: Its changing voltages generate the electrical signals detected at the body surface.

• Long QT syndromeNarrower topic: Its ventricular-cell recovery phase is prolonged in long QT syndrome.

• Ventricular tachycardiaNarrower topic: Ventricular tachycardia begins when cardiac action potentials propagate abnormally.

• Torsades de pointesNarrower topic: Prolonged cellular action potentials help explain the delayed repolarization associated with torsades.

• DefibrillationNarrower topic: A shock affects the electrical activity underlying coordinated cardiac contraction.

• DigoxinRelated: Digoxin’s ionic effects alter cardiac excitability and conduction.

• VerapamilRelated: Calcium-channel blockade alters the plateau and nodal depolarization involved in cardiac signaling.

• AmiodaroneNarrower topic: Amiodarone alters the electrical signals that shape this cycle.

• Brugada syndromeNarrower topic: Brugada syndrome alters the currents shaping electrical activity in heart muscle cells.

• Willem EinthovenBroader topic: The combined electrical activity of cardiac cells generates the signals his instrument recorded.

• Sick sinus syndromeRelated: Altered pacemaker-cell electrical activity underlies abnormal impulse formation.
