This is arguably one of the most important chapters throughout this course. At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals. A...

Blood pressure: normal values and deviations Depending on age, different blood pressure values are considered “normal”. If there are deviations, the systolic and diastolic values are usually either increased or decreased together. However, there can also be a deviation of only one of the two va...
In the study, we conducted experiments to differentiate the severity of coronary stenosis using ECGs based on a one-dimensional deep convolutional neuron network (1D CNN) structure, which has been verified to perform well on ECG-related tasks [31,32,33]. The input layer of the model structure...

Patients with typical presentation of myopericarditis were excluded on the basis of young age, no cardiac risk factors but recent acute febrile illness, chest pain characteristic of pericardial involvement or pericardial friction rub, diffuse ST segment changes but no Q waves on the ECG and ...
Describe the effect that an inhaler medication has, on an asthmatic patient. Do all the spirogram values return to "normal?" Why do you think some values do not return all the way to normal? How well What are the diagnoses of adrenal insufficiency?
