Q

Q

Heart block

A

A condition in which electrical impulses are conducted in the normal fashion from the Atria to the ventricles. May be caused by damage or disease processes within the heart.

26
Q

Hemodynamics

A

The force involved in circulating blood through the cardiovascular system. The heart adapts its hemodynamic performance to the needs of the body, increasing the output of blood when muscles are working and decreasing the output when the body is at rest.

27
Q

Holter monitoring

A

A technique for the continuous recording of electro cardiographic signals, usually over 24 hours, to detect and diagnose ECG changes.

Also called ambulatory monitoring.

28
Q

ICD

A

Abbreviation for the implantable cardioverter defibrillator. An ICD is an implanted device to use to treat abnormal, fast heart rhythms. Several types of therapies are used by the ICD, including cardioversion, defibrillation, and anti-tachycardia pacing.

29
Q

Ischemia

A

Insufficient blood flow to tissue due to blockage in the blood flow through the arteries

30
Q

Lead

A

In an ICD system, the wire or catheter which conducts energy from the ICD to the hard and from the heart to the ICD

31
Q

Left ventricular dysfunction

A

A heart condition in which the heart is unable to maintain normal cardiac output due to a deficiency in the left ventricle

32
Q

Myocardial infarction

A

Death to a portion of the heart muscle tissue due to a blockage or interruption in the supply of blood to the heart muscle

33
Q

Myocardium

A

The middle and thickest layer of the heart wall, composed of cardiac muscle

34
Q

Premature atrial contraction (pac)

A

A contraction in the atrium which is initiated by an ectopic focus and occurs earlier than the next expected normal size beat

35
Q

Premature ventricular contraction (PVC or VPD)

A

A contraction in the ventricle which is initiated by an ectopic focus and occurs earlier than the next expected normal sinus or escape rhythm beat

36
Q

Sinoatrial node (SA)

A

The heart’s natural pacemaker located in the right Atria. Electrical impulses originate here and travel through the heart causing it to beat

37
Q

Sudden cardiac death (scd)

A

Death due to cardiac issues within 1 hour of onset of symptoms, with no warning.

38
Q

Supraventricular tachycardia (SVT)

A

A rapid heartbeat originating from above the ventricles

39
Q

Syncope

A

Fainting, loss of consciousness, or dizziness which may be due to a change in cardiac rhythm (arrhythmia) or other causes.

A transient, self-limited loss of consciousness, is among the most common reasons for visiting an ED

40
Q

Tachycardia (tachyarrhythmia)

A

Rapid beating of either or both chambers of the heart, usually defined as a rate over 100 beats permitted.

41
Q

Ventricle

A

One of the two lower Chambers of the heart

42
Q

Ventricular fibrillation (VF)

A

Very fast, chaotic, quivering heart contractions that start in the ventricles. During VF, the heart does not feed properly. This often results in fainting. You’ve left untreated. It will result in cardiac arrest. Blood is not pumped from the heart to the rest of the body. Death will occur if defibrillation is not initiated within 6 minutes of onset of VF.
