Understanding Cardiac Arrhythmias Quiz

Cardiac arrhythmias can lead to inadequate blood flow, causing shortness of breath.

Resting heart rate within this range indicates a healthy cardiovascular system.

Bradycardia can lead to inadequate blood flow, causing fatigue and dizziness.

ECG records the heart's electrical activity, aiding in diagnosing arrhythmias.

Untreated arrhythmias can lead to blood clots, increasing the risk of heart attack.

Exertional arrhythmia can be triggered by increased demand for oxygen during exercise.

Systolic hypertension refers to high blood pressure, not an irregular heart rhythm.

Atrial flutter is characterized by rapid, regular contractions of the atria.

SA node initiates electrical signals, coordinating heart contractions.

Beta-blockers slow heart rate and reduce the force of heart contractions, managing atrial fibrillation.

Hypokalemia disrupts the heart's electrical activity, leading to arrhythmias.

Ventricular fibrillation leads to ineffective pumping of blood, resulting in sudden cardiac arrest.

Smoking damages the cardiovascular system, increasing the risk of arrhythmias.

Ventricular tachycardia can lead to inadequate blood flow, causing loss of consciousness and even death.

ICD delivers a shock to restore normal heart rhythm in ventricular arrhythmias.

Palpitations may indicate arrhythmias and should be evaluated by a healthcare professional.

Atrial fibrillation increases the risk of stroke and other complications due to ineffective atrial contractions.
