Term
Pericardium

Pericardial effusion
Definition
Around the Heart

fluid or infection around heart
Term
Diastolic
Definition
Relax and refill of the atria and ventricle
Term
Cardiac Output
Definition
Amount of blood pumped from LV each minute
Product of Heart Rate x stroke volume
Term
The heart rate is controlled by the
Definition
ANS
Term
The PNS does what to Heart Rate?

SNS?
Definition
PNS slows

SNS inccreases
Term
Stroke Volume
Definition
amount of blood ejected by LV during each contraction
Term
Preload
Definition
degree of myocardial fiber stre3tch at end of diastole just before the contraction. It determined by amount of blood returning to heart from venous to RA and pulmonary vein (LA)
Term
PreHTN

HTN
Definition
Systolic 120 to 139 and Diastolic 80 to 89 without medication

Syst > OR = TO 140 or Diastolic > or + 90 or taking drugs to control
Term
Causes of Postural Hypotension


Orthostatic Hypotension is defined as
Definition
Cardiovascular Drugs
decreased blood volume
prolong bed rest
Age Related
Disorders of ANS

a drop of 20 or more points from slying to standing

How do you measure Postural Hypotension
Definition
After lying for 3 minutes measure
Then sit or stand wait one minute and auscultate B/P and count radial pulse

Term
Pacemaker of the Heart

Where is it located
Definition
Syno-Atrial Node

RA
Term
Conduction System of Heart
Definition
SynoAtrial Node in RA, intiates contraction goes between A and V to AtriaVentricular Node - AV Node - down septum around each side simultaneously through Perkenje Fibers and permeates all of heart muscle and causes impulse initiates contraction
Term
Indication of the body that something in conduction system not working properly
