Greater that 140/90 Beta blockers - Answers Medication to decrease the force and rate of contraction of the heart, eg, atenolol. Treats high blood pressure Vasodilators - Answers Medications used to reduce the pressure in the vasculature, eg, Norvasc, Lisinopril, Diovan. Treats high blood pressure Diuretics - Answers Medications to reduce the volume of fluid in the system (HCTZ, Lasix) promotes excretion of urine and decrease of blood volume. treats high blood pressure Congestive heart failure - Answers A clinical syndrome due to heart disease and characterized by breathlessness and abnormal water and sodium retention, resulting in edema Digitalis - Answers A pharmacologic agent used to treat congestive heart failure, A fib, atrial flutter and paroxysmal tachycardia. It increases the force of cardiac contraction Left sided heart failure - Answers Left side of heart fails to pump blood out into the circulation efficiency, causing blood to back up to the LUNGS Right sides heart failure - Answers Right side of the heart fails to pump blood efficiently to the lungs, causing blood to back up in the peripheral circulation, causing peripheral edema Congenital heart disease - Answers Cardiac disease caused by a defect in the heart structure since birth Arrhythmia - Answers Any variation from the normal rhythm of the heartbeat Dysrhythmia - Answers Disturbance of cardiac rhythm Normal sinus rhythm - Answers The normal rhythm of the heart containing P waves, QRS complexes and T waves with a regular rate of 60-100 bpm P wave - Answers A wave appearing on an ECG tracing that reflects the electrical activity that produces contraction of atria. The 1st elevation on the ECG. QRS complex - Answers An element appearing on an ECG tracing that reflects the activity that produces ventricular contraction. The heart is at rest. It is narrow and has a width of less than half of one large block T wave - Answers The ECG wave form that represents repolarization of the ventricles PR interval - Answers From the beginning of the p wave to the beginning of the r wave is less than the width of 1 wide block Automaticity - Answers A condition of being automatic Ectopic focus (foci) - Answers A displaced central point of origin for a cardiac dysrhythmia Supraventricular foci - Answers Central points of origin of dysrhythmias, which are located above the level of ventricles in the atria Ventricular focus(foci) - Answers A displaced point of origin for a dysrhythmia that is in the ventricles Sinus rhythms - Answers Cardiac rhythms in which the pacemaker is the sinoatrial node Atrial (Supraventricular) rhythms - Answers Dysrhythmias in which the pacemaker is in the atria above the level of the ventricles (Supraventricular) area. Ventricular rhythms - Answers Cardiac dysrhythmia in which the pacemaker is in the ventricles rather than in the SA node Arrest rhythms - Answers Cardiac rhythms in which there is a cardiac arrest. Some arrest rhythms such as pulseless ventricular tachycardia are accompanied by a rhythm display, but there is no contraction Rate of firing in the SA node - Answers 60-100 Rate of firing in the atria - Answers 60-80 Rate of firing in the AV node - Answers 40-60 Rate of firing in the ventricles - Answers 20-40
