Regularity: irregularly irregularHeart Rate: atrial rate greater than
350 BPM, any ventricular rateP wave: wavy baseline, P waves rarely or
never visiblePR interval: not measurableQRS complex: All the same shape,
less than 0.12 seconds
Regularity: always regularHeart Rate: 100-180BPMP wave: 1 per QRS, all
the same shape, different from sinus P waves in some or all leadsPR
interval: 0.12-0.20 secondsQRS complex: all the same shape, less than
0.12 seconds
One of the most common dysrhyhmias. often found in patients with
chronic lung disorders, such as emphysema or COPD, and in patients with
numerous cardiac disorders, including previous heart attacks or heart
valve disease. Atrial tissue quivers, or fibrillates. classified as
slow, controlled, or rapid(uncontrolled). these rates correspond roughly
to the normal ranges for sinus rhythm. a slow ventricular rate is less
that 60 BPM and is sometimes caused by patients taking digoxin to
another medication intended
is an uncommon tachydysrhythmia responsible for fewer than 10% of
tachycardias with narrow QRS complexes, like sinus atrial tach has P
waves and narrow QRS complex, however, there are significant
differences. Distinguished by the shape of the P waves in certain leads.
Most rhythms below 160 are considered sinus tachycardia
regularity: usually regularHeart Rate: atrial rate 250-350 BPM, and
ventricular rate, but usually 60-100P wave: all the same shape, but can
be distorted by T-wave or QRS (normally a "sawtooth" pattern)PR
interval: not measurableQRS complex: all the same shape, less than 0.12
