, Cardiac ischemia is indicated by
depressed t waves
Cardiac injury is indicated by
elevated ST segment
What can cause inverted t waves
digitalis toxicity and hypokalemia
What causes spiked t waves
hyperkalemia
This rhythm creates a series of identical p waves that take on a sawtooth
appearance.
Atrial flutter
This rhythm occurs when multiple ectopic foci are firing almost continuously and
produces an irregular baseline with no visible p waves and irregular QRS
complexes
Atrial fibrillation
Cardiac infarction is diagnosed by
significant q waves
Which heart block is identified by prolonged P-R interval?
1st degree AV block
Which heart block is characterized by increasingly longer PR intervals until a
missing QRS
2nd degree AV block Mobitz 1 (Wenchebach)
longer, longer, longer, drop, then you got a wenchebach
Which heart block is characterized by missing QRS
2nd degree AV block Mobitz II
If some P's don't get through, you have a mobitz type 2
Which Heart block is characterized by an atrial rate greater than 60, and a
ventricular rate less than 40? The PR interval cannot be determined and the QRS
is widened
3rd degree AV block
If P's & Q's dont agree, then you have a 3rd degree
