Sudden, transient loss of consciousness with loss of postural tone.

The flow of blood in the brain, critical for consciousness.

The pressure that drives blood flow to the brain; calculated as CPP = MAP - ICP.

Average blood pressure in a person's arteries during one cardiac cycle.

The pressure inside the skull that affects brain function.

Cerebral perfusion pressure; determined by MAP - ICP.

Factors leading to decreased cardiac output, impacting blood flow.

Abnormally slow heart rate, leading to reduced cardiac output.

Loss of consciousness due to decreased cardiac output from arrhythmias.

Abnormally fast heart rate leading to low stroke volume.

Elevated intracranial pressure due to conditions like edema or tumors.

Conditions affecting blood flow to brain due to lack of nutrients.

Rapid heartbeats originating from the ventricles, causing output issues.

Seizure activity resulting from reduced blood flow to the brain.

Seizures involving altered consciousness and varying motor activity.

Basic tests required during diagnostic evaluations.

Listening to heart and lung sounds through a stethoscope.

A 24-hour ambulatory ECG to catch intermittent arrhythmias.

Certain dog breeds prone to sudden death from heart issues.

Conditions leading to low CPP include cardiac issues and metabolic abnormalities.

Syncope that occurs in specific circumstances, often with identifiable triggers.

Temporary decrease in blood flow to the brain, causing loss of consciousness.

Signs including rhythmic movements, unexpected symptoms before onset, and prolonged disorientation.

Early symptoms indicating an impending seizure, like unusual sensations or feelings.

Length of loss of consciousness: syncope typically lasts 5-20 seconds; seizures last longer.

Rapid recovery of consciousness in syncope vs. slow return with confusion in seizures.

Need to evaluate characteristics and circumstances of the event for accurate diagnosis.

A heart condition seen in Boxers that increases sudden death risk.

Increased pressure in pulmonary arteries impairing heart function.

Physical abnormalities in heart structure causing dysfunction.

Heart condition with enlarged chambers and poor contractility.

Condition with thickened heart walls reducing filling space.

Blockages in heart valves or vessels affecting blood flow.

Deoxygenated blood bypasses lungs, lowering oxygen levels.

Common congenital heart defect with four specific defects.

A condition causing slow heart rate due to excitement or stress.

How well the left ventricle fills with blood before contraction.

Volume of blood the heart pumps per minute; crucial for perfusion.

Low blood volume in ventricles reducing stroke volume and CO.

Blood flow to the brain necessary for function and consciousness.
