Low voltage generally refers to QRS complex amplitude: The addition of sinus tachycardia is concerning for pericardial tamponade. The combination of low QRS voltages and electrical alternans is highly suggestive of massive pericardial effusion. Manifestations of disease will only be evident when tachyarrhythmias arise. Direct conduction from atria to ventricles via the accessory pathway, bypassing the AV node, seen with atrial fibrillation of atrial flutter in conjunction with WPWġ5% of cases of WPW exhibit retrograde conduction only – as such, they are a “concealed pathway” on the ECG during sinus rhythm.Formation of a reentry circuit involving the accessory pathway, termed atrioventricular reentry tachycardias (AVRT).The presence of an accessory pathway predisposes patients to tachyarrhythmia formation. Our patient above has a type B pattern – a dominant S wave in V1 indicates a right-sided accessory pathway. The type A pattern is associated with a left-sided accessory pathway and manifests a dominant R wave in V1 that may mimic right ventricular hypertrophy. There are two types of precordial patterns seen on the sinus rhythm ECG – type A and type B. When there is abnormal depolarisation there should be abnormal repolarisation - hence the presence of T-wave inversion and ST elevation and/or depression, which can often mimic Occlusion Myocardial Infarction (OMI). Note that tall R waves may mimic ventricular hypertrophy but are simply a result of abnormal depolarisation through an accessory pathway. in the opposite direction to the major component of the QRS complex ST-segment and T-wave discordant changes – i.e.I do fine up until the 7/8 time after the part that eases you into it, from there it just feels impossible to follow because the “glitching” of the audio track just seems TOO overdone for its own good and even just closing my eyes and listening for it there’s literally no stable rythm to follow. I don’t get it, I get so close to the end every time and the. Also I feel like sometimes I’m hitting on beat but the game still judges is at too early for some reason though that’s more of a general thing. ![]() Not sure if the timing is just that strict even on normal difficulty or if it’s a synch issue.Įdit: finally got it by tapping to the rythm on my off hand but just barely, I feel like the game did a great job with incorporating the rythm in with the gameplay to where things can get tricky but still make sense rhythmically (even with the glitch stuff for the most part) UNTIL this level, I feel like I’m just keeping 7/8 time on my own even though the song just goes off the deep end and I’m just keeping my own imaginary time instead of playin a rythm game. Originally posted by fizzd:Thanks for the feedback! You're totally accurate in getting our intentions with the level. ![]() For this one I wanted to explore what if we edged towards needing the player to keep the beat all by themselves. In the other glitch levels the downbeat is pretty sacred, meaning we make sure to avoid glitching on the first beat of the bar, so there's always a reference point. In this one, by the end we break the rule to make the player really need to fight to keep the beat. ![]()
