The 12 Rhythms of Christmas: Paroxysmal AV-Block

Entry Img

This article is the ninth in our latest series, The 12 Rhythms of Christmas, where we examine a different rhythm disorder with each new post. It’s a continuation of the theme behind last year’s 12 Leads of Christmas. And, just like last year’s series, I’m rather late getting the final articles out, but the end […]

The 12 Leads of Christmas: V3

Entry Img

This is the eleventh and penultimate article in our latest series, The 12 Leads of Christmas, where each day we examine an individual electrocardiographic lead. Lead V3 Today we’re going to discuss V3, and there’s no way I can do that without talking about isolated posterior myocardial infarction. Of all twelve, fifteen, eighteen, or even […]

The 12 Leads of Christmas: V2

This article is the tenth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead. Lead V2 I love V2.

Entry Img

This article is the ninth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead.

The 12 Leads of Christmas: V4

Entry Img

This article is the eighth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead.

The 12 Leads of Christmas: aVR

Entry Img

This article is the fifth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead. Lead aVR I have a love-hate relationship with aVR. There is one big question that always looms around it: Is ST-elevation in aVR a STEMI-equivalent? Like most […]

The 12 Leads of Christmas: aVF

Entry Img

This article is the fifth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead. Lead aVF I dug myself quite a hole on this one as there’s really not much to say about aVF. It’s located midway between leads II and […]

The 12 Leads of Christmas: aVL

Entry Img

This article is the fourth in our latest series, The 12 Leads of Christmas, where each day we examine a new finding particular to an individual electrocardiographic lead. Lead aVL Today’s  review is going to be light on text (but heavy on EKG’s) to make time for Wednesday’s big post on aVR. It also helps that […]
