P-wave duration and atrial fibrillation recurrence after catheter ablation: a systematic review and meta-analysis

“… 2–12 , 14 , 15 , 17–20 , 22 , 23 Patients with AFr had longer PWD with a mean pooled difference (ΔPWD) of 7.8 ms ( P < 0.001, Figure 2 ). Subgroup analysis revealed that the ΔPWD remained significantly different in patients measured only with ECG (13 studies, ΔPWD 7.01 ms, P < 0.001) 6–10 , 14 , 15 , 17–20 , 22 , 23 or only with SAECG (6 studies, ΔPWD 10,22 ms, P < 0.001). 2–5 , 11 , 12 The difference between ECG and SAECG studies was not statistically significant ( P = 0.46).…”

“…The association between PWD and the incidence of AFr was calculated after identifying the number of patients having specific PWD and AFr in each study. The pooled OR was 2.04 (1.16–3.58) for PWD > 120 ms (13 studies, P = 0.01), 6–10 , 13–15 , 17–23 2.42 (1.12–5.21) for PWD > 140 ms (2 studies, P = 0.02), 6 , 23 3.97 (1.79–8.85) for aIAB (5 studies, P < 0.001), 6 , 13 , 14 , 19 , 23 and 10.89 (4.53–26.15) for PWD > 150 ms (4 studies, P < 0.001), 3 , 6 , 15 , 16 revealing that the risk for AFr increased significantly from >120 to >130 and >140 and excited that of advanced IAB when the PWD was over >150 ms ( Figure 3 ).…”

“…Yang et al . 23 found that an MVP >3 has the best predictive ability for AFr (c-statistics 0.789), but this index requires additional measurements of low-amplitude P-waves in Lead I and was not directly compared with PWD alone.…”

Role of the Electrocardiographic MVP Risk Score (Morphology-Voltage-P Wave Duration) in Predicting the Development of Atrial Fibrillation in Patients With Systemic Arterial Hypertension

“…The MVP ECG risk score is correlated to interatrial block, 8 and in addition, it is associated with left atrial dilatation and electromechanical atrial dysfunction. [9][10][11][12][13][14] Therefore, it is associated with the atrial substrate responsible for the formation of atrial thrombi and cerebral embolism, [15][16][17] which is an extremely serious and disabling complication. Stroke episodes cause innumerable costs to public health and reduce the years of useful life of the affected people, 4,18,19 hence, it is extremely important to be able to incorporate this MVP ECG risk score in our daily practice, to stratify adequately the risk of patients, to perform an appropriate therapeutic management, and to be able to individualize the long-term follow-up.…”

“…In this effort, various atrial variables were studied, [36][37][38] including the characteristics of the P wave, thus validating the MVP ECG risk score. 6,8,9,14 Previously, the MVP ECG risk score was studied for AF prediction, and it was based on MVP. 6 They studied a heterogeneous population without AF who underwent coronary angiography and followed them for 12 months.…”
