ECG Quiz on LearnTheHeart.com - more than 200 ECG tracings with detailed answers. Beginner and expert.
To master ECG interpretation takes time and effort, however the LearnTheHeart.com ECG tutorial is designed to be concise and focused on only what you need to know, yet very thorough. Start by reading through the ECG basics and the different parts of the ECG. Once completed, be sure to read through all of the ECG criteria and review pages to learn how to diagnose specific conditions and rhythms such as myocardial infarctions and chamber hypertrophies. Then go through the 100+ practice ECG quizzes below that have detailed explanations and link to the pertinent explanation pages. Then there are ECG cases which test your ECG interpretation skills in the setting of clinical scenarios. Once completed, a thorough understanding of ECG interpretation will be attained. Keep your skills up by signing up for our ECG Blog.
The ECG quizzes on LearnTheHeart.com are organized as below:
From basic 12-lead ECG tracings to the most bizarre expert level tracings, this ECG test is excellent for all levels of ECG interpretation skills. Nearly 200 tracings are currently included each with detailed explanations and links to relevant topic reviews for each ECG.
Most challenging and unusual ECG tracings including rare electrophysiologic disorders. Even the ECG gurus of the world will be challenged by some of these tracings!
Simple findings such as the most common rhythm disorders, infarctions, blocks and chamber enlargements.
AV blocks, bundle branch blocks, and sinoatrial exit blocks. Links to comprehensive reviews for all heart block topics are included to enhance the learning experience.
Atrial fibrillation, atrial flutter, atrial tachycardia, varying SVTs and junctional rhythms. Every derivation of atrial arrhythmias is included with detailed explanations and links to pertinent reviews.
Rhythms originating in the ventricles such as ventricular tachycardia (monomorphic and polymorphic), ventricular fibrillation and premature ventricular contractions. Some SVT with aberrancy ECG tracings are included to help enhance the discussion of how to diagnose ventricular tachycardia. Detailed explanation are included with links to the relevant topic reviews.
Anterior MI ECGs, inferior MI ECGs, posterior MI ECGs and other ischemic ECG changes. All ECGs have detailed explanations and links to relevant topic reviews. Test yourself on these ECG tracings regularly since quick diagnosis is important.
Left and right atrial enlargements, left ventricular hypertrophy, right ventricular hypertrophy and more. Detailed explanations and links to topic reviews are included.
Unusual ECG findings such as hyperkalemia, other electrolyte disturbances and rare findings. These include hypothermia and rare electrophysiologic conditions. Detailed explanations are provided with links to topic reviews.
These ECG tests are quite extensive, but it is important to complete all of the tracings to attain a full ECG education. Review then once every few months to keep these ECG principles fresh in your mind. Join the LearnTheHeart.com ECG Blog for regular postings of ECG Cases.
This is awesome creature is the caterpillar form of Phylllodes imperialis, the Imperial Fruit Sucking Moth. The moth is found in parts of Australia and a few neighbouring island countries. The markings on its head that resemble a mask sporting giant eyes and a wonderfully freaky skeletal grin are used to frighten off potential predators.

science side of tumblr, please explain
Air on bottom go woosh. Air on top go woosh. Air on front go woosh. Little plane stay still.
I’ve seen this photograph very frequently on tumblr and Facebook, always with the simple caption, “Ghost Heart”. What exactly is a ghost heart?
More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won’t survive the wait. Last year, 340 died before a new heart was found.
The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.
Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor - a box with artificial lungs and tubes that pump oxygen and blood into it - and wait as the ghost heart begins to mature into a new, beating human heart.
Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this— first using rat hearts, then pig hearts and human hearts - for years.
The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place.
This scaffold of connective tissue - called a “ghost organ” for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.
This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart - one that won’t be rejected - can be grown.
This is the coolest fucking thing ever. Science, man. Fucking science. Shit completely blows me away.
sorry sir, we don’t have the facilities for a cat scan, but we can certainly get you a lab report
A purpuric rash as a result of Neisseria infection. The Neisseria is a Gram-negative diplococcus which contains a lipooligosaccharide component to its outer membrane that acts as an endotoxin. It results in the purpuric rash when the immune system targets the bacteria for destruction, scattering the lipooligosaccharide through out the vascular system causing damage to the vascular walls and creating the purpura seen here. This particular type of purpura can be used to identify Neisseria because it’s non-blanching; if you pressed against the purpura the color will stay the same.
