Pathway of Electricity
This node. known as the heart's natural pacemaker, initiates the heartbeat.
What is the SA node?
The chamber that receives blood from the body and passes it to the right ventricle.
What is the right atrium?
This arrhythmia causes a fast, irregular heartbeat in the atria.
What is atrial fibrillation?
This diagnostic tool records the electrical activity of the heart.
What is an ECG or EKG?
This device is implated to regulate abnormal heart rhythms.
What is a pacemaker?
This structure delays the electrical signal, allowing the ventricles to fill with blood before contracting.
What is the AV node?
The thick muscle wall that separates the left and right sides of the heart.
What is the septum?
A complete block at this node prevents signals from reaching the ventricles.
What is the AV node?
A heart rate of over 100 beats per minute is classified as this.
What is tachycardia?
Medications such as bets-blockers are used to control this heart rhythm disorder.
What is tachycardia or atrial fibrillation?
These fibers spread the electrical signal throughout the ventricles.
What are Purkinje fibers?
The layer of the heart wall responsible for electrical conduction.
What is the myocardium?
This arrhythmia causes the ventricles to contract too quickly, leading to reduced cardiac output and can be life- threatening if untreated.
What is the ventrricular tachycardia?
This ECG finding indicates a delaayed conduction through the AV node.
What is a prolonged PR interval?
This emergency device delivers a shcok to restore normal heart rhythm.
What is a defibrillator?
Name the pathway of electricity through the heart, starting with the SA node.
What is 1. SA node, 2. AVnode, 3. Bundle of His, 4. Purkinje fibers?
This part of the heart pumps oxgenated blood to the rest of the body.
What is the left ventricle?
A slow heat rate, often due to conduction system defecr, is known as this.
What is bradycardia?
This rhythm is characterized by a chaotic, disorganized electrical activity in the ventricles.
Whar is ventricular fibrillation?
This treatment is often required for complete heart block.
What is pacemaker implantation?
This bundle branches into the left and right pathways to conduct impulses through the ventricles.
What is the Bundle of His?
The coronary arteries provide blood flow to this vital organ.
What is the heart?
This condition occurs when the electrical impulses in the atria are completely disorganizes, resulting in a loss of coordinated atrial contraction.
What is atrial fibrillation?
This ECG abnormality, characterized by an elevated segment, is often a sign of this serious cardiac event.
What is a myocardial infarction?
Catheter ablation targets and destroys these to treat arrhythmias.
What are abnormal electrical pathways?
