What is atrial flutter? What does it look like?
Atrial flutter is a self perpetuating loop of conduction, usually in the right atrium. The atrial rate is REGULAR and RAPID with a BPM of 250 - 400. Ventricular rate is 1/3 slower due to the AV node blocking some of the atrial impulses. Ventricular rate is usually regular but can also be irregular. Characterized on ECG by absense of normal p-wave and instead “flutter waves” or f-waves/ a sawtooth pattern prior to the QRS complex.
What is atrial fibrillation? What does it look like?
Atrial fibrillation is due to multiple electrical impulses from many ectopic sites in and around the atria, often near pulmonary vein roots. The impulses are unsynchronized and random causing atria to quiver (fibrillate) rather than contract. Most impulses do not pass to the ventricles. Atrial rate can be very fast. Ventricular rate is IRREGULAR, ranging from less than 60 to more than 100 BPM. Characterized on ECG by absent P-waves and narrow, irregular QRS complexes. Baseline may be flat or appear undulating. Flat indicates MORE conduction impulses from atria.
What is ventricular tachycardia? What does it look like?
V-tach is due to a single strong firing site/circuit in one of the ventricles. Usually occurs in people with structural heart problems such as scarring from a prior MI or heart muscle abnormalities. Impulses originating in the ventricles produce premature ventricular contractions that are REGULAR and FAST ranging from 100-250 BPM. Characterized on ECG with no P-wave and wide, undulating QRS complexes – it looks like large, regular humps. Sustained V-tach longer than 30 seconds requires immediate intervention to prevent cardiac arrest. It can quickly progress to V Fib
What is ventricular fibrillation?
V-fib is caused by multiple weak ectopic impulses in the ventricles causing them to fibrillate/quiver rather than contract. This means no blood is being pumped out of the heart. Quickly leads to cardiac arrest . Characterized on ECG as irregular, random wave forms with no identifiable waves or complexes.

First degree heart block
Look at space between P and QRS. If it longer than 1/2 a big box, consider a 1st degree
“if the R is far from P, then you have a first degree” –in first degree block, the PR interval is longer than 0.20 seconds
Second degree heart block type I
“longer, longer, longer, drop! Then you have a Wenkebach” –in Mobitz Type I, the PR interval progressively lengthens until a beat is dropped, and then the process resumes again.
“March out” the P waves –they’re regular because the atrial rate is regular but the P to QRS interval lengthens and then occasionally the QRS drops out entirely
Second degree heart block type II
“If some Ps don’t get through, then you have a Mobitz II” –in Mobitz Type II, the PR interval remains constant/no lengthening but occasionally, the QRS complex doesn’t happen. Look for multiple Ps in a row with no QRS complex.
Third degree heart block
LETHAL RHYTHM “If Qs and Ps do not agree, then you have a third degree” –Atrial signals are not getting through, ventricle is generating escape impulse independently of atria, so atria is beating 60-100 BPM and ventricles beating 30-45 BPM asynchronously. Looks like a weird P-QRST with occasional long intervals between complexes. This is a high priority finding due to risk of decompensation into cardiogenic shock or periods of asystole. Tx atropine and temp pacing until permanent pacemaker can be placed.
Ps might be hidden behind Ts making them a little larger collectively, Ps are regular.
QRS are also regular. March out both to notice where the Ps are hidden behind the Ts. The atrial and ventricular rates are not coordinated at all.
Note: easy to confuse with 1st degree

Pyloric stenosis
Hypertrophy of pyloric muscle causes postprandial projectile vomiting due to obstruction at gastric outlet. Palpate olive shaped mass to the right of the umbilicus. Vomiting is non-bilious (whatever is eaten is vomited) and leads to progressive dehydration and results in hypokalemic metabolic alkalosis. Hemoconcentration due to dehydration results in elevated hematocrit and BUN.

IV insulin is titrated down as the blood glucose returns to an acceptable range and may be discontinued when it is below 200 mg/dl. IV potassium will be administered even if normokalemic to prevent common complication of hypokalemia d/t insulin causing shift of K from intravascular to cellular space and resulting life threatening arrythmias that can result.
Risks for fat embolism
Long bone fracture –look for dypnea/confusion/decreased Sp02, petichiae on trunk
Calcium channel blockers ending and common side effects
-ipine –vasodilators so cause decrease in blood pressure and can result in dizziness, flushing, headache, peripheral edema, and constipation. Can initially cause orthostatic hypotension so pt teaching should include slow position changes.
Tetracyclines teaching
Take on an empty stomach, avoid iron supplements, dairy and antacids, take with a full glass of water and remain upright after taking to reduce chances of pill induced stomach upset (i.e. don’t take at bedtime), can cause photosensitivity, and it decreases the effectiveness of oral contraceptives so another method must be used while taking.

Hospice vs palliative care
Palliative focuses on quality of life and managemnet of symptoms. Can be given even with curative or life-extending treatment in the setting of a terminal diagnosis. Involves a multidisciplinary care team for the pt and family. Hospice is started when treatment is discontinued. Palliative is not limited to a specific time frame re: life expectancy.
