Let's solve the EKG Chapter Matching worksheet step by step. We'll match each numbered statement with the correct lettered answer from the list on the right.
---
1. An ____________ records the electrical activity of the heart.
→ A. electrocardiogram
*Explanation:* An electrocardiogram (ECG or EKG) is a test that records the electrical activity of the heart over time.
2. The average adult heart rate is ____________.
→ L. 60-100 bpm
*Explanation:* Normal resting heart rate for adults is between 60 and 100 beats per minute (bpm).
3. The passage of O₂ and nutrients to the body takes place in the ____________.
→ F. capillaries
*Explanation:* Capillaries are tiny blood vessels where gas exchange (O₂ and CO₂) and nutrient transfer occur between blood and tissues.
4. The ____________ transport blood from the ventricles to the aorta and then to all parts of the body.
→ G. arteries
*Explanation:* Arteries carry oxygenated blood away from the heart (from the left ventricle to the aorta and then throughout the body).
5. An irregular heart rhythm is also known as an ____________ or dysrhythmia.
→ I. arrhythmia
*Explanation:* Arrhythmia means abnormal heart rhythm; it’s synonymous with dysrhythmia.
6. A fast heart rate is ____________.
→ B. tachycardia
*Explanation:* Tachycardia refers to a heart rate greater than 100 bpm.
7. A slow heart rate is ____________.
→ S. bradycardia
*Explanation:* Bradycardia is a heart rate below 60 bpm (in adults).
8. An ____________ is a test used to analyze the size, shape and movement of the structures inside the heart.
→ C. echocardiogram
*Explanation:* An echocardiogram uses ultrasound to visualize heart structure and function.
9. ____________ is a blood test performed to determine myocardial damage.
→ T. Troponin levels
*Explanation:* Troponin is a protein released into the bloodstream when heart muscle is damaged (e.g., during a heart attack).
10. ____________ are the best indicators for myocardial damage.
→ T. Troponin levels
*Note:* This is a repeat of #9 — troponin levels are considered the most specific markers for myocardial injury.
11. A ____________ is the device attached to the BP cuff to measure an arterial blood pressure.
→ O. sphygmomanometer
*Explanation:* A sphygmomanometer is the instrument used to measure blood pressure (includes the cuff and gauge).
12. The ____________ is the pacemaker of the heart.
→ R. sinoatrial node
*Explanation:* The SA node generates electrical impulses that initiate each heartbeat.
13. ____________ is a condition in which the myocardium or heart muscle is not receiving a sufficient amount of O₂ and blood supply.
→ P. Myocardial Ischemia
*Explanation:* Ischemia means inadequate blood flow; myocardial ischemia leads to chest pain (angina) and can cause infarction if prolonged.
14. The word part "emia" means ____________.
→ M. blood condition
*Explanation:* "-emia" comes from the Greek "haima" meaning blood; e.g., anemia = lack of blood, hyperemia = excess blood flow.
15. The heartbeat is controlled by the ____________ nervous system.
→ D. Autonomic
*Explanation:* The autonomic nervous system (specifically the sympathetic and parasympathetic branches) regulates heart rate and rhythm.
16. ____________ is an excessive amount of fatty substances in the blood and can contribute to atherosclerosis.
→ J. Hyperlipidemia
*Explanation:* Hyperlipidemia refers to high levels of lipids (cholesterol, triglycerides) in the blood, leading to plaque buildup.
17. The numerator of a blood pressure is called the ____________. This is the contraction phase of the ventricles.
→ N. systolic cycle
*Explanation:* Systolic pressure is the top number in blood pressure (e.g., 120 in 120/80), representing pressure during ventricular contraction.
18. The denominator of a blood pressure is called the ____________ or relaxing phase of the heart cycle.
→ U. diastolic
*Explanation:* Diastolic pressure is the bottom number, representing pressure when the heart relaxes between beats.
19. Hypotension is blood pressure less than ____________. Symptoms may include headache, dizziness, nausea, vomiting, syncope, difficulty concentrating.
→ Q. 90/60 mmHg
*Explanation:* Hypotension is generally defined as blood pressure below 90/60 mmHg.
20. A portable device which records a patient's EKG for 24 hours is called a ____________.
→ K. holter
*Explanation:* A Holter monitor is a wearable device that continuously records ECG for 24 hours or longer.
21. A ____________ is a physician who specializes in the study of the heart.
→ H. Cardiologist
*Explanation:* A cardiologist is a doctor specializing in heart diseases and conditions.
