Instructor: Ahmed Zaafran, MD - (23:26) - 0.75 CME
Presenter: Ahmed Zaafran M.D.
In this video we discuss following topics about myocardial ischemia:
Coronary blood supply vs. cardiac demand for the blood.
Pathophysiology and types of myocardial ischemia are discussed.
Stable vs unstable angine.
Dr. Syed presents the first chapter in the series of the EKG Interpretation lectures. This chapter contains:
1. EKG waves.
2. EKG segments.
3. EKG intervals.
4. Various shapes of the QRS complex and how to articulate them.
5. EKG paper properties.
Dr. Syed presents the first session in the series of supraventricular extrasystole.
Topics covered are:
Atrial Premature Beat/Premature Atrial Contraction (PAC)
Junctional Premature Beat
Difference between the Junctional Premature Beat and the Junctional Escape Beat
Blocked Atrial Premature Beat
Lecture 2 part 2
Dr. Syed continues the discussion of arrhythmias. In this talk he discusses:
Identifying Atrial Ectopic Rhythms on the EKG
Identifying Junctional Ectopic Rhythms on the EKG
Identifying Ventricular Ectopic Rhythms on the EKG
Abnormal Uterine Bleeding can impair activity and function in women of many ages. This lecture by Dr. Ahmed Zaafran explores the causes of AUB and the effective clinical treatment regimens for patients with abnormal uterine bleeding.
This lecture presents the management approach for the patients presenting with diabetic Ketoacidosis.
Following management methods and the principles behind the management are explained:
Volume replenishment, volume types, the reason for choosing various types, benefits of the volume replenishment, and the complications of aggressive volume replenishment.
Insulin administration. Caution for insulin administration when potassium levels are low. The amount of insulin to administer and the rate of fall of glucose levels.
Why do insulin and glucose need to continue even after a good glucose level has been established?
What to expect in terms of potassium levels? How to manage potassium? How to correlated potassium levels to insulin and volume?
What labs and signs and symptoms to monitor and how to adjust when ref-flags show up?
How to approach bicarb deficiency?
Diabetic Ketoacidosis (DKA) is the second most common presentation of type 1 diabetes mellitus. (First most common being early onset diabetes mellitus.)
In this second part of the lecture we discuss:
Mechanism of the gastrointestinal (GIT) symptoms.
Bicarb levels in DKA.
A quick comparison of the metabolic disturbances in DKA and HHS.
The impact of acidosis and membrane potential predisposing cell to arrhythmias.
Metabolic picture of DKA.
Working up the labs' data for DKA patient.
Calculating expected PaCO2 levels using Winter's equation.
Diabetic Ketoacidosis (DKA) is the second most common presentation of type 1 diabetes mellitus. (First most common being early onset diabetes Mellitus.)
In this first part of the lecture we discuss:
The reason for the higher propensity of type 1 diabetes mellitus patients to develop DKA.
The role of Insulin, Glucagon, Epinephrine, and Hormone Sensitive Lipase is discussed.
Potassium level disturbance in patients presenting with DKA.
Mechanism of acidosis in DKA.

Chest X-Ray is a routine clinical investigation. It is important for healthcare professionals to be comfortable approaching and interpreting it. In this webinar, Dr. Alikhan shares his excellent method to identify key elements that are frequently encountered on the chest x-ray..
Instructor: Luis Verduzco, MD - (01:06:31) - 1.5 CME
In this video, we review clinically pertinent respiratory anatomy and physiology as it relates to obstructive lung disease. Functional residual capacity, hypoxic pulmonary vasoconstriction and flow loops are reviewed. Obstructive pulmonary disease is discussed with an emphasis on emphysema and its pathophysiology, diagnosis and acute treatment during exacerbations.
This video discusses: Atmospheric gas pressures Water vapor pressure and its effect on the atmospheric pressure Pressure changes during inspiration Composition of the exhaled gases Factors affecting partial pressure of the oxygen Factors affecting partial pressure of the carbon dioxide
This video presents Bronchiectasis a type of obstructive lung disease. Bronchiectasis is irreversible, chronic, dilatation of the bronchi and bronchioles due to or associated with the chronic infectious disease process.
Instructor: Luis Verduzco, MD - (46:09) - 1.25 CME
In this video, we discuss the physiology of potassium homeostasis as well as the mechanisms used by the body to maintain a stable potassium concentration. Three clinical examples of hyperkalemia are noted. The acute and subacute management of this life-threatening disorder is discussed.
Instructor: Luis Verduzco, MD - (01:05:55) - 1.5 CME
In this lecture, we review sodium homeostasis in the human body as well as hyponatremia. Critical care management of hyponatremia is discussed. The differential diagnosis of hyponatremia will be outlined and an approach to its etiology is reviewed.
In the perioperative cardiac complications lecture, we describe multiple cardiac and non-cardiac complications of cardiac surgery; an anatomic and organ system approach is taken to describe the cardiac and non-cardiac issues, respectively. A special emphasis is placed on heparin-induced thrombocytopenia as well as intra-aortic balloon pumps. After this lecture, learners should feel significantly more comfortable in the cardio-vascular ICU.
Dr. Syed starts the series about the peripheral nerve disorders with this foundational lecture. In this lecture Dr. Syed presents:
Structure of a neuron
Structure and composition of a peripheral nerve
6 principle categories of the nerve pathology
6 medical terms to depict nerve disorders
6 causative agents of the nerve disorders
