This term refers to profuse sweating.
What is diaphoresis?
Drugs that promote the excretion of excess fluid from the body belong to this classification.
What are diuretics?
This is the point where the QRS complex ends and the ST segment begins.
What is the J-point?
The blood vessels that carry oxygen-rich blood from the lungs to the heart are these.
What are the pulmonary veins?
This vessel type is the only vein to carry oxygenated blood.
What is the pulmonary vein?
This is the term for fainting.
What is syncope?
Atorvastatin (Lipitor) belongs to this medication class.
What are statins? (antilipemics)
This ECG artifact appears as jagged peaks with irregular height and spacing.
What is somatic tremor artifact?
This technique uses ultrasonic waves to study heart structure and motion.
What is echocardiography?
This phase of the heartbeat is known as the contractive phase.
What is systole?
This condition occurs when a blood clot forms in a vein deep in the body.
What is deep vein thrombosis?
Furosemide (Lasix) is part of this medication class.
What are loop diuretics?
This artifact occurs when the tracing starts normal but becomes erratic due to interrupted electrical connection.
What is a wandering baseline artifact?
This saclike membrane surrounds the heart.
What is the pericardium?
This layer is also known as the visceral pericardium.
What is the epicardium?
Bluish discoloration of the skin, lips, or nail beds is known as this.
What is cyanosis?
Amlodipine (Norvasc) belongs to this class of medications.
What are calcium channel blockers?
When artifact appears on Leads I and III, this electrode should be checked.
What is the right arm electrode?
This type of shock occurs when the heart is too damaged to pump effectively.
What is cardiogenic shock?
This structure is the natural pacemaker of the heart.
What is the sinoatrial (SA) node?
This progressive disorder involves degeneration of the heart muscle.
What is cardiomyopathy?

What is an anticoagulant reversal agent?
These ECG leads are placed across the chest wall and are also called precordial leads.
