A 70-year-old male with a past medical history of hypertension and chronic obstructive pulmonary disease (not on oxygen) presented to the emergency room with complaints of shortness of breath of 3 months duration. Shortness of breath was gradual in onset and progressive in nature and associated with intermittent vague chest pain. He denied associated diaphoresis and nausea but admits to pedal edema and 3 pillow orthopnea. Physical exam was remarkable for the obese male not in acute distress. Bibasilar crackles were noted. 2 + pitting pedal edema. JVD was also noted. The patient was admitted to medicine. Iv Furosemide 60 mg iv was started. The next day 2D echocardiogram was done which revealed anterior wall motion abnormalities. Cardiology was consulted. The patient subsequently underwent cardiac catheterization which revealed a heavily calcified lesion involving ostial to mid part of the left anterior descending artery. An attempt at stent placement was unsuccessful. A decision to proceed with rotational atherectomy was done. What would be the optimal rotational speed for rotational atherectomy and the duration of ablation during each pass through the coronary artery?

I would like to share with you about SVTs, or supraventricular tachycardia, today. I'll be focusing on the pathophysiology, ECG features, and the management of SVT today. So this is a brief outline of the lecture today. I will be going through the definition of SVTs, followed by a brief classification of tachyarrhythmias, the pathophysiology behind it all, ECG features, and management principles of SVTs. I will round off the lecture with a clinical scenario related to the topic. This lecture is meant to be a basic introduction to SVTs, and is by all means not exhaustive. So without further ado, let us begin. Supraventricular tachycardias are defined as narrow complex tachycardias where the point of stimulation arises from above the bundle branches. There are many types of SVTs, as will be shown in the next slide, and some are more common than the others. However, in our local context, it is used interchangeably with proximal supraventricular tachycardias, which make up a...
If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...
