n.心肌（层）

原形：myocardium复数：myocardia

The myocardium is the muscular tissue of the heart responsible for pumping blood throughout the body.
心肌是心脏中负责将血液泵向全身的肌肉组织。
In a healthy individual, the myocardium exhibits rhythmic contractions to maintain circulation.
在健康个体中，心肌会表现出有节奏的收缩以维持血液循环。
Damage to the myocardium can lead to heart failure or arrhythmias.
心肌损伤可能导致心力衰竭或心律不齐。
A myocardial infarction, commonly known as a heart attack, occurs when blood flow to the myocardium is blocked.
当流向心肌的血液受阻时，会发生心肌梗死，通常被称为心脏病发作。
The thickness of the myocardium may be increased in response to chronic hypertension.
长期高血压可能会导致心肌增厚。
The echocardiogram allows visualization of the myocardium and its motion during the cardiac cycle.
超声心动图可使我们在心脏周期中观察到心肌及其运动情况。
Ischemia, or reduced blood flow to the myocardium, can cause chest pain and shortness of breath.
心肌缺血（即心肌供血减少）可引起胸痛和呼吸急促。
Cardiomyocytes are the muscle cells that make up the myocardium in the heart.
心肌细胞是构成心脏中心肌的肌肉细胞。
Stem cell therapy holds promise for repairing damaged myocardium following a heart attack.
干细胞疗法有望在心脏病发作后修复受损的心肌。
An electrocardiogram (ECG) measures the electrical activity generated by the myocardium.
心电图（ECG）测量由心肌产生的电信号。
