Martins, Breedloves, go to the back of the line! Comments about Takamine GB-7C Garth Brooks Signature Acoustic-Electric Guitar: Professional guitarist who plays all the time. I don't just play a gig every now and then, I do studio work, gigs, play in a band, recordings with other artist, etc. So, since this is what I do, I have to have the best equipment for sound and playability.
Changes in LBBB during ischemia. In case of a left bundle branch block (LBBB), infarct diagnosis based on the ECG is difficult. The baseline ST segments and T waves tend to be shifted in a discordant direction with LBBB, which can mask or mimic acute myocardial infarction.
The criteria (Sgarbossa [1]) that can be used in case of a LBBB and suspicion of infarction are: 1  ST elevation > 1mm in leads with a positive QRS complex (concordance in ST deviation) (score 5)  ST depression > 1 mm in V1-V3 (concordance in ST deviation) (score 3)
