Toxicities terms for Cardiac disorders
Myocarditis
A disorder characterized by inflammation of the muscle tissue of the heart.
Palpitations
A disorder characterized by an unpleasant sensation of irregular and/or forceful beating of the heart.
Paroxysmal atrial tachycardia
A disorder characterized by a dysrhythmia with abrupt onset and sudden termination of atrial contractions with a rate of 150-250 beats per minute. The rhythm disturbance originates in the atria.
Pericardial effusion
A disorder characterized by fluid collection within the pericardial sac, usually due to inflammation.
Pericardial tamponade
A disorder characterized by an increase in intrapericardial pressure due to the collection of blood or fluid in the pericardium.
Pericarditis
A disorder characterized by irritation to the layers of the pericardium (the protective sac around the heart).
Pulmonary valve disease
A disorder characterized by a defect in pulmonary valve function or structure.
Restrictive cardiomyopathy
A disorder characterized by an inability of the ventricles to fill with blood because the myocardium (heart muscle) stiffens and loses its flexibility.
Right ventricular dysfunction
A disorder characterized by impairment of right ventricular function associated with low ejection fraction and a decrease in motility of the right ventricular wall.
Sick sinus syndrome
A disorder characterized by a dysrhythmia with alternating periods of bradycardia and atrial tachycardia accompanied by syncope, fatigue and dizziness.
Myocardial infarction
A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
Sinus bradycardia
A disorder characterized by a dysrhythmia with a heart rate less than 60 beats per minute that originates in the sinus node.
Supraventricular tachycardia
A disorder characterized by a dysrhythmia with a heart rate greater than 100 beats per minute that originates above the ventricles.
Tricuspid valve disease
A disorder characterized by a defect in tricuspid valve function or structure.
Ventricular arrhythmia
A disorder characterized by a dysrhythmia that originates in the ventricles.
Ventricular fibrillation
A disorder characterized by a dysrhythmia without discernible QRS complexes due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricles.
Ventricular tachycardia
A disorder characterized by a dysrhythmia with a heart rate greater than 100 beats per minute that originates distal to the bundle of His.

Sinus tachycardia
A disorder characterized by a dysrhythmia with a heart rate greater than 100 beats per minute that originates in the sinus node.
Mobitz type I
A disorder characterized by a dysrhythmia with a progressively lengthening PR interval prior to the blocking of an atrial impulse. This is the result of intermittent failure of atrial electrical impulse conduction through the atrioventricular (AV) node tothe ventricles.
Mobitz (type) II atrioventricular block
A disorder characterized by a dysrhythmia with relatively constant PR interval prior to the block of an atrial impulse. This is the result of intermittent failure of atrial electrical impulse conduction through the atrioventricular (AV) node to the ventricles.
Mitral valve disease
A disorder characterized by a defect in mitral valve function or structure.
Aortic valve disease
A disorder characterized by a defect in aortic valve function or structure.
Asystole
A disorder characterized by a dysrhythmia without cardiac electrical activity. Typically, this is accompanied by cessation of the pumping function of the heart.
Atrial fibrillation
A disorder characterized by a dysrhythmia without discernible P waves and an irregular ventricular response due to multiple reentry circuits. The rhythm disturbance originates above the ventricles.
Atrial flutter
A disorder characterized by a dysrhythmia with organized rhythmic atrial contractions with a rate of 200-300 beats per minute. The rhythm disturbance originates in the atria.
Atrioventricular block complete
A disorder characterized by a dysrhythmia with complete failure of atrial electrical impulse conduction through the AV node to the ventricles.
Atrioventricular block first degree
A disorder characterized by a dysrhythmia with a delay in the time required for the conduction of an electrical impulse through the atrioventricular (AV) node beyond 0.2 seconds; prolongation of the PR interval greater than 200 milliseconds.
Cardiac arrest
A disorder characterized by cessation of the pumping function of the heart.
Chest pain - cardiac
A disorder characterized by substernal discomfort due to insufficient myocardial oxygenation e.g., angina pectoris.
Conduction disorder
A disorder characterized by pathological irregularities in the cardiac conduction system.
Cyanosis
A disorder characterized by a bluish discoloration of the skin and/or mucous membranes.
Heart failure
A disorder characterized by the inability of the heart to pump blood at an adequate volume to meet tissue metabolic requirements, or, the ability to do so only at an elevation in the filling pressure.
Left ventricular systolic dysfunction
A disorder characterized by failure of the left ventricle to produce adequate output.
