Q

Atrial fibrillation

A

Rate:
Artia 100-175
What is the rhythm:
Irregular irregular
Is there a P wave before each QRS:
Normal waves are absent
Are the P waves upright and uniform:
Replaced by F wave (sawtooth)
What is the length of the PR interval:
No discernable
Do all the QRS complexes look alike:
Yes

< .12 (3 small squares)

Atrial fibrillation is an irregular and often wrapping heart rate that occurs when two upper chambers of your heart experience chaotic electrical signals. The result is a fast and irregular heart rhythm. The heart rate in atrial fibrillation may range from 100 to 175 BPM

Q

Atrial flutter

A

Rate:
250-300

Yes
The length of the QRS complex:
Usually <.12 (3 sm sq)

Israel flutter is a type of heart rhythm disorder in which the heart’s upper chambers beat too quickly. In atrial foot of your heart’s upper Chambers be too quickly as causes a hard to be too fast but usually regular rhythm.

Q

First degree AV block

A

Rate:
Based on the rate of the under rhythm

Is there a P wave before each QRS:
Yes

< 0.12 (3 sm sq)

Air condition of abnormal slow conduction through the AV node. It is defined by ECG changes that include PR interval of greater than 0.20 without disruption of atrial or ventricular conduction. This conduction is generally asymptomatic and discovered only in a routine ECG.

Q

Junctional

A

Rate:
40-60

Not measurable
Do all the QRS complexes look alike:

Occurs when the electrical activation of the heart originates near or within the AV node, rather than the SA node. Because the normal ventricular conduction system, his dash per junkie, is used. The prx complex is frequently narrow

Accelerated junctional rhythm is faster than junctional rhythm. Heart rate ranges from 60 to 100
